Error on vB?

Anyone care to help..

Wth is happening? when i try to save changes to my CSS stylesheet through my admincp (vBulletin), this error occurs,

Required variables have gone missing and execution can not continue. Please try again.

This error can sometimes occur as a result of Suhosin / Hardened PHP being installed on your server. If you know that you have Suhosin running and you have access to the PHP configuration, try increasing the value of the following variables:
php_value suhosin.post.max_vars
php_value suhosin.request.max_vars



EDIT PROBLEM SORTED, IGNORE THREAD


anyone know what it could be, my host is looking at it atm but i wonder if it could be something else

LOL, your probably using a pirated version. Why wouldn't you just go to the vbulletin forum where you get a response in two minutes?
