Trackback and Pingback not doing anything... (41 posts)

    Forgive the ignorance I am about to show here.

    Ok...so I have built a blog on WordPress.
    I believe it's 2.0.1

    I have enabled the following options:
    Attempt to notify any Weblogs linked to from the article (slows down posting.)
    Allow link notifications from other Weblogs (pingbacks and trackbacks.)
    Allow people to post comments on the article

    I can see "incoming links" on the dashboard ... but nothing shows up in the comments as trackbacks.

    Here are the factors that may be complicating things.

    1) Link format.
    The support thread I read that was a similar issue had to do with the format of the trackback link.
    While this may be an issue... shouldn't the pingback functionality STILL work?
    I have tried both methods with no luck.
    But for the sake of compete disclosure...

    I have chosen the permalink format of:
    The trackback URLS seem to show up as:

    When I place the trackback URL into a browser window I get:
    The document has moved here.
    To be honest I'm not sure if that's supposed to happen or not.
    I EXPECTED to end up at the permalink page.

    So that may be an issue...
    But even if it is why would the pingbacks not be working?

    2) I have anti comment spam plugins running.
    Specifically Bad Behavior & Captcha!
    Not sure if those affect the pinkback / trackback functions - but there's nothing showing up as needing to be moderated or anything.

    3) I am using a custom theme.
    It's also completely feasible that I am missing something in the templates I have created.
    I have added the following code to the single post page:
    <!--<?php trackback_rdf(); ?> -->
    and I have added the meta tag
    <link rel="pingback" href="http://mydomain.com/xmlrpc.php" />
    In my header I have also included the following code:
    <?php wp_head(); ?>

    Is there anything else I should be doing?

    First off, 2.0.1 is old and had issues. Among other things, security issues. You'll probably want to update to 2.0.7 or 2.1 before you waste too much time.

    Secondly, and you may know this but I'm not sure from reading above, pingbacks/trackbacks are shown when OTHER blogs link back to you. (more http://codex.wordpress.org/Introduction_to_Blogging#Trackbacks )

    And you may indeed see "Incoming links" on the dashboard and not a corresponding trackback. Incoming links are pages that have your url on 'em. Those sites may not have actually issues a pingback or trackback though.

  3. DougYITBOS

    Understand that they are incoming.
    I have another site running wordpress that does attempt to notify other blogs (pingback)

    From that blog I have tried just linking in the body (to fire off a pingback) and specifically using the trackback URL in the trackback are of the post page.

    neither are showing up at the other site.
    Though they do apparently show up as incoming links.

  4. Whether or not other sites send you pingbacks/trackbacks is really up to those other sites. All you can do is allow it or disallow it.

    The "incoming links" is courtesy of technorati.com and has nothing to do with trackbacks and pingbacks.

  5. DougYITBOS
    Posted 9 years ago #

    ok... sorry I must not be being very clear.

    I OWN the site that is sending the trackback as well.
    it IS allowed there.

    I mention the incoming links just as a side note.

    The point here is...
    from a site that I can verify DOES attempt to send pingback and trackback info... I can't get it to show up.

  6. Chris_K

    I'll mention my first point again: Update to current versions for both sites before wasting too much time on diagnosis.

  7. DougYITBOS
    Posted 9 years ago #

    Duly noted.
    It's a stellar idea and I shall do that in the near future.
    BUT... This most likely doesn't boil down to a version issue there are people on this version that have trackbacks working.
    ...and I need to troubleshoot this before a new install. :(

    Would appreciate anyone who can chime in with ideas on how I can resolve the issue with the current version.

    DougYitbous, seems that we're having the same problem. For me, the problem has persisted with every upgrade through 2.0.7. I've tried to solve it at times, unsuccesfully, as described in these threads:


    Let me know if you find a solution.

  9. DougYITBOS
    Posted 9 years ago #

    Thanks halsnalle.
    I will pass along any info I find - please do the same.

    Come on there are obviously some wicked smart people here.
    +8,000 cool points to the one that figures this out.

    I just used http://www.tamba2.org.uk/wordpress/TestTrack/ to test my OUTBOUND trackback and pinkbacks.
    They went out and were accepted by the destination site as expected.
    So my problem is purely RECIEVING trackbacks and pingbacks.

  11. Pingbacks:

    1. On your blog, do you have this sort of thing in the header of the html?
    <link rel="pingback" href="http://example.com/blogdirectory/xmlrpc.php" />
    The relevant code to generate this should be in your theme's header as this:
    <link rel="pingback" href="<?php bloginfo('pingback_url'); ?>" />

    2. Does the xmlrpc.php file exist?

    Beyond that, there's really little to check. If you're running a spam blocker like Akismet or Bad Behavior, check to see if they are blocking the pingbacks.

    Trackbacks are a bit more direct. Somebody has to use your trackback URI, which maps to the /wp-trackback.php file. Make sure it's there and accessible.

  12. DougYITBOS
    Posted 9 years ago #

    yup the pingback link tag is in there.
    xmlrpc.php is there and accessible.

    Trackbacks don't even work.
    I have tried referencing the wp-trackback.php file directly... no luck.

    At the site that SENDS the ping or trackback the url referenced shows up in the "already pinged" list.

    Nothing Errors out... but nothing shows up at the site that us supposed to get the trackback.

    This may drive me mad.

    Hej där,

    Turns out that after upgrading to 2.1 I receive spam trackbacks... Always a start. No non-spam ones so far, but I'll keep my fingers crossed that it just works all of a sudden.

  14. DougYITBOS
    Posted 9 years ago #

    ok I upgraded to 2.1

    Still can't RECIEVE trackbacks or pingbacks.
    I can send them out just fine.

    :( wth is going on...

  15. DougYITBOS
    Posted 9 years ago #


    now on 2.1
    got trackback and ping backs to work but had to disable ALL plugins and also make sure the the author's name and email was NOT required.

    If I enabled Akismet things still worked... but anything else or anything + Akismet killed trackbacks and pingbacks. (and in this case too I had to make sure the the author's name and email was NOT required.)

    I know there are sites out there that use Akismet and Bad Behavior as well as require email and name. They have Trackbacks showing up like crazy.

    So... any ideas.
    Any one...
    I'll send you a cigar...

    I've also recently upgraded to 2.1 and am having the same troubles as Doug.

    By simply disabling Akismet and unchecking the author name/email box, trackbacks starting working but not pingbacks. (receiving trackbacks.)

    All this is present and correct:


    1. On your blog, do you have this sort of thing in the header of the html?
    <link rel="pingback" href="http://example.com/blogdirectory/xmlrpc.php" />
    The relevant code to generate this should be in your theme's header as this:
    <link rel="pingback" href="<?php bloginfo('pingback_url'); ?>" />

    2. Does the xmlrpc.php file exist?

    I also have a testblog running on 2.1 with the identical theme as the blog I'm having problems with. Turning off all plugins enabled be to send and receive trackbacks, but pingbacks still wouldn't work. Switching themes to default also had no effect.

    So, I have one blog that can only receive trackbacks by doing the same as Doug, but can't send them or receive or send pingbacks. The testblog with no plugins and the default theme can only send and receive trackbacks and can't do anything with pingbacks.

    Both blogs are also redirecting the /trackback/ to its permalink when you click on the trackback link, irrespective of what theme is used.

    I'll up the ante and send anybody a box of cigars. ;-)

    We are experiencing the same problems with incoming pings and trackbacks. Upgraded to WP 2.1, disabling the plugins didn't solve the problem. Al files and references are OK.

    I'll send anybody a sixpack of Heineken to wash away the tatse of the cigars. ;-)

    To add something to despair, another blog of mine, running the same version and the same plugins (on antother server) does receive and process pings and trackback nicely...

    I am having a similar issue. I have WP 2.1.2 and I can't get any pings to be sent out, not even to the updaters (i.e. Blogrolling, My Yahoo, etc.) I also cannot send pings to other WP blogs, including another one I set up to test it out. When writing a post and indicating to send a ping, it shows up on the post editor a ping has been sent out, but nothing was actually sent.

    I've been a nearly three year user of WP and never run into this problem, and I have all the code that was suggested above and in other threads. I also tried to disable Askimet to no avail, but that was grasping at straws since it was an error of sending pings out, not receiving them.

    Any help would be much appreciated.

    ADDED: For clarification purposes, I can ping posts within my blog, but for whatever reason nothing goes to other blogs or ping services.

    Recently I have discovered that pings sent by a hand-made PHP script are being processed and stored by WordPress. Pings from other WordPress blogs however are not.
    I have also tried to send a ping from a Microsoft Live Space but I'm not shure iif Microsoft supports sending pings to non-Microsoft blogs.

    I use 2.0.9 and still cannot send out trackbacks :(

    I did some tests:
    I send a trackback to all linked posts under each test.

    I just upgraded to WordPress v2.1.2 and am experiencing the same inability to send pingbacks as almost everyone else here.

    Update: I can send trackbacks, but I still can't send pingbacks.

    My issue with sending pingbacks appears to be caused by a "pre-release" version of Fauna RC 2 as pingbacks are successfully sent whenever the Default theme is used instead of Fauna. I'll update this thread when I know more.

    Well, Pingbacks are succesfully sent from my Blog but receiving pingbacks is not functioning. The system isssues a 403 error...
    I think I'll dig into the source code sometime

    Same deal here. My ability to send pingbacks comes and goes intermittently; more often not at all. Trackbacks go out just fine.

    Question, is there way to manually send a pingback? I am at a loss here.

    Sussed it... after a month I realised that I had edited a post's date and time and accidentally set it to the future - once that was changed to a date in the past, pingbacks jumped into life.

    Well, I'm having those problems to. Can someone please give us some explanation?

    I am having problems too ... I started a month ago with WordPress 2.1.2 and a few days ago upgraded to 2.1.3. I am administrator of 2 WordPress blogs so I can test that way.

    I self-ping fine. I ping to her blog fine and I have done those things since the beginning. I think I have been pinging other places fine but not sure.

    I have this morning gotten it right to trackback from one of our blogs to the other. (I was using the url when I clicked on url - and so it had no /tracbacks/ at the end) (this site helped me figure that out http://www.tamba2.org.uk/wordpress/ping/)

    I have been trying for a few days to trackback to a typepad site who wants a trackback. She has gotten a trackback from another typepad site.

    But I haven't been able to do it with hers .. I used her url that was given for trackbacks for that post and I also added a /trackback/ on the end in case that was a problem.

    I have spent hours looking at support posts and I don't know what to do from here ...

    any help is appreciated!

    I think the wonderful guy, Adam Kalsey, at SimpleTracks figured it out.

    I wasn't doing it right on from one of my blogs to the other by not having the /trackback/ on the end. I am still not sure if I am supposed to add /trackback/ when another site has /trackback/ in the middle of their trackback.

    But Adam figured out that the site that wanted my trackback was making me do a captcha check and ... by trackback that wasn't going to happen. So whew! It wasn't me (hopefully) - so now I need to see if a friend wants a trackback to test.

    So thank you!! and good luck!!

    I'm having troubles with trackbacks after upgrading from 2.1.2 to 2.1.3.

    Site: http://spiralbound.net

    Accept pings is enabled on all posts.

    I can send pingbacks to my own stories from my own stories. (place a link to story2 in the test of story1 and get a pingback on story2 after a save.)

    I can not sent trackbacks from my own stories to my own stories. (enter the URL to story2 in the "Send trackbacks to" field on story1). It shows up as sent, but no trackback shows up on story2.

    Nobody can send me trackbacks or pingbacks from external sites. (link in text or using the "Send trackbacks to" field).

    I am running a new theme, but I switched back to my old theme, and the exact same behavior is seen. I don't see any 404's, or errors in either error_log or access_log.

    php -v
    PHP 4.3.9 (cgi) (built: Sep 21 2006 07:08:09)
    Copyright (c) 1997-2004 The PHP Group
    Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies
    with the ionCube PHP Loader v3.1.16, Copyright (c) 2002-2006, by ionCube Ltd.

    I am wondering if someone can chronicle what happens when a trackback or pingback is sent so that I can trace and confirm at each step.

    Thanks for any help you can offer.
