This is the answer to the session issue:
To run PHP sessions, include the following code at the top of any PHP script that uses sessions:
session_save_path("your home directory path"/cgi-bin/tmp);
To find "your home directory path":
Log into the PHP Scripting page for actual path to your home directory.
Replace "your home directory path" with the path shown.
Set session_save_path to a directory within your cgi-bin: either /cgi-bin/tmp as in the example above or another directory as long as the absolute path is correct.
I should just be able to add the /cgi-bin/tmp path into the php.ini, right?
