Title: Trackbacks error Last modified: August 18, 2016 --- # Trackbacks error * [herby007](https://wordpress.org/support/users/herby007/) * (@herby007) * [22 years, 2 months ago](https://wordpress.org/support/topic/trackbacks-error/) * I tested the “trackback-function” with some ohter Blogs (pivote, MT and so on). But there is no link, if I give at my entry the permanent-link in the trackback- line below the textarea. In the options menu-section “RSS/RDF Feeds, Track/Ping- backs” it is all “true”. And the pings to “blog.ws” and “weblogs.com” works fine. Where could be the error? Thank yo so much!

It works now fine with a MovableType-Blog.

When I was running b2 my blog only showed a few trackbacks. When I moved the blog over to WordPress the number doubled. The entries in MySQL seemed fine. I’m yet to really test them with my new wordpress install. * [atmasphere](https://wordpress.org/support/users/atmasphere/) * (@atmasphere) * [22 years, 2 months ago](https://wordpress.org/support/topic/trackbacks-error/#post-42251) * I can’t seem to get trackbacks to work… I know I’ve sent a few from posts I’ve made on my blog, but have yet to see them show on the other sites. * [atmasphere](https://wordpress.org/support/users/atmasphere/) * (@atmasphere) * [22 years, 2 months ago](https://wordpress.org/support/topic/trackbacks-error/#post-42290) * Trackbacks are totally hosed… I am not seeing them appear at all on any site. I try to linkback when I can (if available on a site) and I’ve been checking lately and not seeing anything. * Thread Starter [herby007](https://wordpress.org/support/users/herby007/) * (@herby007) * [22 years, 2 months ago](https://wordpress.org/support/topic/trackbacks-error/#post-42297) * Atmasphere: I think, the trackbacks works with MT and WordPress. If you want to make a test, you (and any other reader here) can take this entry from my blog: [http://medienfakten.de/content101/wp-trackback.php/106](http://medienfakten.de/content101/wp-trackback.php/106) And you’ll see thr result at [http://medienfakten.de/content101/index.php?p=106](http://medienfakten.de/content101/index.php?p=106) I’ll take a back-trackback to your entry. * [atmasphere](https://wordpress.org/support/users/atmasphere/) * (@atmasphere) * [22 years, 2 months ago](https://wordpress.org/support/topic/trackbacks-error/#post-42300) * just did a test to you and I am not seeing anything at the page. * Anonymous * [22 years, 1 month ago](https://wordpress.org/support/topic/trackbacks-error/#post-42360) * Me neither. Also, when I try to add a trackback to an already published post, I get an error: Fatal error: Call to a member function on a non-object in … / wp-includes/class-xmlrpc.php on line 760 * [alhague](https://wordpress.org/support/users/alhague/) * (@alhague) * [22 years, 1 month ago](https://wordpress.org/support/topic/trackbacks-error/#post-42361) * OK, one Problem with trackback in WP is that someone seems to have forgotten that some blogs do need to receive a query-Part in the trackbacked URI. I have changed one line in wp-includes/functions.php: was: $http_request = ‘POST ‘. $trackback_url[‘path’].” HTTP/1.0\r\n”; is: $http_request = ‘POST ‘.$trackback_url[‘ path’].”?”.$trackback_url[‘query’].” HTTP/1.0\r\n”; and have now sucessfully pinged a pivot-powered blog. * [underblog](https://wordpress.org/support/users/underblog/) * (@underblog) * [22 years, 1 month ago](https://wordpress.org/support/topic/trackbacks-error/#post-42364) * I’m still not getting my trackbacks through after alhague’s fix. Is it possible it could be a server problem, since most people don’t seem to be having an issue with this? I can recieve but not send using the 5th may nightly.
