  • Hey mjhubba,

    First check your functions.php and see if there’s any white space outside of <?php ?>. If there’s any white space, remove it and see if it helped.

    Second try adding the code below in the functions.php


    For more details, check out this page.

    Hi geeksfolder
    There were no real white spaces and that code was already in there. So no change. Any other tips?
    Thanks for your help.

    Check your wp-config.php as well if there’s any white space.
    Also if you have any cache plugin installed, remove the cache.

    If you are still getting the problem, check your PHP version.
    PHP 5.2.2 seems having some issues with XML Phrasing.
    Try add

    $HTTP_RAW_POST_DATA = file_get_contents("php://input");

    in xmlrpc.php.
    Please note, though, as xmlrpc.php is a core file, it’s not a perfect solution.

    Hi thanks for your help. I’m sorry but this is going to be very painful reading to anyone who knows anything about PHPs!!

    I’ve checked the wp-config. And that’s ok. I don’t think I have any cache plugins – I can’t see any in the list of plugins that say cache. I presume they would mention cache in the plugin title.

    I am on 404PHP. I can not see anything that says xmlrpc.php – where do I find that? And when I do where would I add the
    $HTTP_RAW_POST_DATA = file_get_contents(“php://input”); ? I’m not sure where exactly I would place it in file.

    Also, out of the blue at 10am this morning (I was nowhere near the computer) I got two emails to tell me about new posts on my blog. So somehow the feed started working (although I only got it on one email address I had subscribed with). However, when I went to my webpage I pressed subscribe and nothing seemed to happen. I then went into Dashboard and the RSS Widget and fiddled around and now the RSS icon and Subscribe are not showing again. AAARrrrr.

    Thank you if you made it this far!

    Any ideas?

    Has the theme you are currently using been heavily modified by yourself or someone else?

    You should try switching to a default theme (like Twenty Eleven) to see if that fixes the feed, just so you can narrow it down to that.

    Hi JerrySarcastic
    The site is currently using Twenty Eleven HOWEVER previously I have changed themes …

    Me again.
    I have re-fiddled and now the Subscribe and icon is appearing on I do not know why or how.
    Can anybody spare a min and look at this and tell me whether it’s working for them? I fear the icon is there but it’s not actually doing anything.
    Thanks so much.

    You still have a number of blank lines at the top of your RSS feed which is invalidating the entire feed. Have you tried:

    – deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

    – switching to the Twenty Eleven theme to rule out any theme-specific problems.

    resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

    – re-uploading the wp-admin and wp-includes folders from a

    I’ve deactivated all the plugins and the feed seems to work when I view it in IE. However, when I view in Google Chrome I get this message:
    This XML file does not appear to have any style information associated with it. The document tree is shown below.
    Followed by a very lengthy document.

    Am I getting anywhere? Has deactivating the plugins made it work again? (Sorry cos i’m not even sure what it should look like when it does work, doh!)

    Rather than testing the different browsers, you may want to validate your feed instead. It’s more authoritative.

    I’ve deactivated all the plugins and the feed seems to work when I view it in IE.

    Then you have a bad plugin. Re-activate the plugins one by one – testing the feed in IE after each re-activation – until you find the problematic plugin(s)

    when I view in Google Chrome I get this message

    That’s normal behaviour for Chrome. It doesn’t have a built-in feed reader.

    I say this because I am on Chrome (for Mac) and I got the same message as before, the one you mentioned at the start of the thread.

    JerrySarcastic: I used the validator put in and it said:

    This is a valid RSS feed.

    This feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations.
    line 264, column 0: content:encoded should not contain iframe tag (2 occurrences) [help]

    I am not getting the old message of before.

    Esmi: thanks. Tomorrow I will work through the plugins and find that baddun and then i’m going to OUT it publicly on here!! Thanks for your help.

    So today I have started to see which plugins are baddies. At first I thought I’d found the answer. So the process of elimation began to show that all of the plugins caused a problem. Now i’ve deactivated them again but now i’m back to getting the same error message that I had to begin with – but this time only when viewing in Chrome.
    In IE it seems to be ok, it goes through to a feed page. However, I have subscribed to my feed and it has not been updated even though I added a new post earlier.
    Any ideas?

    I too have having the same error. I will have to check the W3 Cache plugin. I dislike having to use feedburner; I usually use and install a WordPress rss feed.
