note 87899 added to ref.session

hello i have this problem : 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 when i want to change the Theme in the vbulletin se this error . and i crate the .htaccess with this note but dont solve my problem : php_value suhosin.request.max_vars 2048 php_value suhosin.post.max_vars 2048 and the vbulletin say do this , but dont i know to change the server configoration You will need to have your host help you with .htaccess issues as they are outside vBulletin and part of your server configuration. please help me to solve this problem :(( -- Have a wonderful day.
