What are the script requirements? Are there any requirements for the PHP or MySQL version?

Since the script is written in PHP and using a MySQL database, in order to run it on your server or hosting package, you need to have PHP and MySQL installed on it. There are no specific requirements for the versions, but for both we recommend version 5 or newer. In order to use the SEO URLs feature (it's a configuration option in the admin panel) you need to have also mod_rewrite enabled for your hosting package. Today it's almost impossible to find a Linux shared hosting package not supporting PHP, MySQL and mod_rewrite, but if you have any doubts if your current hosting package has these, please don't hesitate to contact us and we'll test it asap for you.
