Works perfectly fine for me... screen shot?

I cleaned my firefox cookies and works fine now...

But, why it give problem because of cookies, since there are no bugs logged in cookies for my forum? Can you explain this problem please?

Try rebuilding your caches in Admincp >> Tools & Maintenance >> Cache Manager

Rebuilt already.. But no effect

The problem is coming about because a thread was probably removed directly from the database and the forum is still trying to search for it hence the error.

Could you also try doing a Recount and Rebuild from the same Tools & Maintenance menu?

Recount done...
Still nothing

PM me phpmyadmin details and a test account that shows the above error and has admincp access.

My problem is not solved yet..
Can anyone help me here?
