I have almost every hack in the book, vb 3.0.7 . The last ones installed before this started happening were
1. Ajax Fast Open Close Threads
2. Moderator Application
3. Quick edit
4. vBFavorite
5. Statistic link in footer
6. Compress Styles
any ideas? Is it a template issue like lastpostinfo, a database issue or a php file error?
I just checked on my other styles and apparently the problem is still there, so it isnt a template issue, must be an error in one of the php files. my question is which one?
