HTTP 403 error
 

Every Time I Try To Edit Something and go to hit save it say forbidden i need some help

Admin CP > Maintenance > Diagnostics > Problematic Modules

Ok and what am I looking for after that?

What do you see? :)

I see 2 boxes with the words No on the side.

So it says "no" under both Suhosin and mod_security?

I have the same error

When I go to check problematic modiles I get:

Suhosin
Módulo Cargado No

mod_security
Problema Unicode AJAX No

The above setting will indicate if mod_security is preventing some AJAX requests from being submitted to vBulletin. If this shows Yes then you either need to disable mod_security or change the AJAX settings with the vBulletin Options and disable Problematic features.
