Trackback always seems to fail

pfaut · Post by **pfaut** » Sat Aug 19, 2006 3:41 pm

It seems no matter what site I link to, Serendipity fails to enter a trackback to that site. I always get the error 'No trackback URI found' even though the page contains a trackback URI. What exactly is Serendipity looking for? How do I troubleshoot this? Is there any logging that can be turned on?

I'm running Serendipity 1.0, PHP 5.1.4-pl0-gentoo, apache-1.3.34.

Do you link to a s9y-blog, too?

The problem: When a blog has a text like "this is my trackback-uri" this is only for humans. Try to add this link in the trackback-plugin, it should work.

The other thing: There is a way to see the trackback-uri by a maschine. s9y can read thuch uri's - but many blogs out there do not have such a maschine-readable uri in the html-source-code; s9y has such a code:

It is a so-called RDF-information:

Code: Select all

<!--
        <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
                 xmlns:trackback="http://madskills.com/public/xml/rss/module/trackback/"
                 xmlns:dc="http://purl.org/dc/elements/1.1/">
        <rdf:Description
                 rdf:about="http://blog.stephan.manske-net.de/feeds/ei_1.rdf"
                 trackback:ping="http://blog.stephan.manske-net.de/comment.php?type=trackback&entry_id=1"
                 dc:title="Ja, hallo erstmal ..."
                 dc:identifier="http://blog.stephan.manske-net.de/archives/1-Ja,-hallo-erstmal-....html" />
        </rdf:RDF>
        -->

That's part of the problem. I have tried pasting that into the trackback plugin and it still doesn't work. It appears to load that page looking for the RDF info rather than using it to post a trackback.

hm,

a) try a link in the normal text-area to

http://mein-test.supersized.org/archive ... test3.html

b) and do in the trackback-field:

http://mein-test.supersized.org/comment ... ntry_id=29

The first one worked. Plugging the second one into the trackback plugin resulted in:

• Checking http://mein-test.supersized.org/comment ... ntry_id=29 for possible trackbacks...
• Trackback failed: No trackback-URI found.

hm,

Code: Select all

• Überprüfe http://mein-test.supersized.org/comment.php?type=trackback&entry_id=29 auf mögliche Trackbacks...
Sende Trackback zu URI http://mein-test.supersized.org/comment.php?type=trackback&entry_id=29...
• Trackback erfolgreich

I just upgraded to the latest - 1.0.1 - and get the same results on the manual trackback entry.

I just went to the Serendipity download site and noticed the trackback-control plugin is currently at version 1.16. My system had 1.5. I upgraded and it appears to work now. Guess that one doesn't get updated with a Serendipity update....

Yes, there are only a few plugins with the core installation. Most of them are downloadable from spartacus and must be updated the same way.

But with the new s9y-version you have two buttons on the top of the plugin-page to see the new plugin versions.
