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

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.

Control Panel - Forums & Moderators - Forum Permissions

It will show you what user group can do what on that forum (where the tread belongs)

That is a server error. Do you have mod_security or suhosin enabled on the site (ask your host, don't guess)?

Hello,

I'Ve asked to my hosting company, and yeah, they're using both.

If there's a cmd for suhosin, they can set for me.

Can you help?

Your host should be able to check the logs and identify the cause of this problem. The logs should tell the exact reason why the request was blocked.
There's not much we can do since we do not have access to your server nor we are in contact with your host.

Apprecieted. Fixed.
