We have enabled suphp mechanism on the server this insures compatibility to php5 and future versions of php. Therefore, please add the php flags to a php.ini file in the folder where you need the customisation, instead of using htaccess.
Example OLD htaccess:
Before you added a line like this to .htaccess
php_value register_globals 1
Remove these lines and add all php_values to a file called php.ini
Example NEW in a php.ini file:
register_globals = On
