Today I noticed that the trackback feature of wordpress ist not working for me.
Since I use permalinks the trackback uri for a post is e.g. http://blog.linsin.de/index.php/archives/2004/11/27/about-me/trackback/ . I can trackback other posts, that means my post appears in the comments of the article I tracked back. What I can't do is let people track back my posts. After trying a couple of things, I changed the trackback uri to http://blog.linsin.de/wp-trackback.php/6 by alterning the code of the file template-functions-comment.php.
I don't know if this is a proper workout, but it works for me!
