Facebook linkback error

[michaelbang]

Every time I put a link on my facebook to a post or thread or video in my vBulletin Forum, it links to my Forum Home on facebook. Why does it alter my link?

If I for example link to mysite.com/forum/showthread.php?100-Fritl%E6gning, then facebook changes to link to mysite.com/forum. Why is that? And can I do something to change that behavior?

Thanks

And are those threads viewable by guests? If not, then facebook can't see them either and will just put a link to your site.

Yes they are. And actually, facebook always links to my "Frontpage", not even my forum. www.mysite.com/forum.

And the only text that shows in facebook is: vBulletin 4.0 Publishing Suite with CMS

What could be wrong?

Disable all Products except the vBulletin Blog and vBulletin CMS (Admin CP -> Plugins & Products -> Manage Products -> Disable) AND uncheck all the plugins except those related to the vBulletin Blog and vBulletin CMS by (Admin CP -> Plugins & Products -> Plugin Manager). You must do BOTH of those steps in order to disable all non vBulletin Modifications. (If you are troubleshooting the Facebook App, then you should leave the product "vBulletin Facebook Register Login" enabled also.)
