thank you for your response.
as to your requests for more info on this issue —
How are you 'sending' these trackbacks?
i can't speak for stergos (hopefully she'll see this and respond also), but for myself, i am doing it just as the wordpress.org support info says to do it, in the trackback field provided by wp-core in the edit post screen. see — http://codex.wordpress.org/Writing_Posts , and http://codex.wordpress.org/Introduction_to_Blogging#Trackbacks , and http://codex.wordpress.org/Introduction_to_Blogging#Pingbacks .
i put my referenced links in that provided trackback field in the edit post screen of wp-core, i separate each link with a space, as it says to do on that edit screen, when there are multiple links. prior to WP 3.4, doing that would notify the non-WP legacy sites that i referenced them just fine. in WP 3.4 & still in 3.4.1, it takes the multiple links, separated by spaces as it says to in the edit post WP screen, and takes out the spaces so it becomes one, long, meaningless garbage line, then attempts to send to that (which is garbage). consequently, the separate non-WP sites never get notified of the trackback.
For example, when I do that, I tend to have an in-line link. In my sentence, I'll link back to the site I'm talking about. I did this just yesterday, and it worked fine, so let's first make sure we're all talking the same thing.
i do that, and for sites that are non-WP, i put links, sometimes multiple ones, separated by spaces, as it says to in that trackback field in the edit post WP screen. that's what you should do. worked fine prior to WP 3.4. in WP 3.4 & 3.4.1, removes the spaces between links on "save draft" or "publish" and the track back links become a smushed together garbage line.
Are you just putting in a raw URL, two in a row, to 'ping' another site?
i am doing this as a trackback, to non-WP sites, as i know WP site are automatically pingbacked. so yes, as it says to in the edit post WP screen in WP-Core, i put in multiple non-WP links i reference and separate them with a space. prior to WP 3.4, this worked fine. in WP 3.4 & 3.4.1, takes out the spaces on "save draft" or "publish" and it becomes a garbage line.
this is easy enough to test. in WP 3.4 or 3.4.1 —
- create a new post in WP
- in the post, have links in-line with your verbiage to non-WP sites, say three of them.
- in the trackback field in the edit post WP screen, put your three or so non-WP site links, separated by spaces, as it says to right on the screen for that trackback field.
- click on "save draft" or "publish."
- go back and look at at the trackback field.
expected result —
in WP 3.3.x and earlier versions, it handled the non-WP trackbacks fine and notified those sites of the links in the post or page to it.
in WP 3.4 & 3.4.1 still, the spaces between the links in the trackback field are removed on "save draft" or "publish" and the multiple link line becomes one long garbage line and WP attempts to notify that, which, of course does not work.
i hope that all answers your queries and makes it clearer to you. please let us no if you have any further questions, but this should be enough to notify WP-Core devs thru trace and post an issue, please.
thank you for your response to this. i hope this moves this along.
