If you're on a server with SUPHP enabled, some PHP options in .htaccess files, such as php_flag or php_value may not work. You need to move these into the PHP script itself, using the PHP ini_set() function. For example,
- change php_flag register_globals On in .htaccess to ini_set("register_globals", "On"); in your PHP script.
- change php_value include_path "dir1:dir2" in .htaccess to ini_set("include_path", "dir1:dir2"); in your PHP script.
If your PHP script still isn't working, please raise a support ticket and we may be able to help.
Also, note that if your script does indeed need flags such as register_globals switched to on, often updating to a newer version of your script would be a good idea. register_globals can indicate a potentially unsecure script.
