Can't saving settings on admin control panel
 

everytime i attempt to change a style or option i get this:

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

any ideas?
