I'm guessing your getting a 500 internal server error, not all servers are configured to allow php flags/values in a htaccess file.

Use this in the htaccess file:

suhosin.cookie.encrypt Off
suhosin.request.max_vars 2048
suhosin.post.max_vars 2048

OR

Create a php.ini file and put it in the required directory:

php_flag suhosin.cookie.encrypt Off
php_value suhosin.request.max_vars 2048
php_value suhosin.post.max_vars 2048
