Hello there,

I've a problem in my forum website.

All threads in another categories and forums can be edited without any problem but under a specific category, no-one except Administrator can edit threads.

They automatically get this warning;

"Forbidden

You don't have permission to access /forum/editpost.php on this server."

What do I need to do?

THanks.
