I see at the top of the thread there is the trackback dropdown.

I'm running vbulletin 3.6.4 and vbseo 3 rc 8 but I can't find an option for this. Do I have to change templates to add this functionality to my site?

Thanks.

It is a setting in your vbseocp.php file. Under Pingbacks/Trackbacks.

I actually renamed it. It was originally Linkbacks and I just did a template edit to name it Trackbacks

I have everything set to yes in that section. I'll have a word over at vbseo.

If you have a customized style that may be causing it since it has to search for a line to input the html.

That makes sense... Is vbseo doing a replacement on some <!-- --> tags?

Yea but I can't remember what it is. I guess that code is inside the actual files. Just looked through the plugins and can't seem to find what they are looking for.
