Please note that the register_globals directive must be off in your PHP setup. If it is on, it is first of all a general security liability, and second, it can cause a number of problems with software coded for register_globals off --- such as the all the odd issues that arose after the recent security patch. Please turn register_globals off in your php.ini file, or ask your host to do it.

You should not use software that requires you to keep register_globals on. It has been deprecated since PHP 5.3.0, and will be entirely removed in PHP 6.0.0. To know if register_globals is on on your server, download the phpinfo script and upload it to your server, then open it in your browser and search for register_globals in the output; it will be "On" or "Off". If it's on, do whatever it takes to turn it off.
