Looks like you have password-protected Roller's Trackback receiver servlet. Unfortunately, Roller's trackback sender cannot handle authentication so that's not going to work.

Hi, I am getting a weird response when I request a trackback. Any help would be greatly appreciated. Rather than: <response> <error>0</error> </response> (per Fig 12 in the user guide), I get a dump of what appears to be /webapp/roller/themes/frontpage/_header.vm (see end of message). I am running Roller 3.1 on Apache Tomcat 5.5.23. Trackbacks used to work on this installation, but I may have broken something somehow while trying to deny access to outsiders (I use the blog for a course and limit it to existing Roller users only).
