Server Modules needed?

Hi Michael,

great plugin, works perfect on my development server. After moving to production server it fails with “Error message: Response cannot be null”. I’m sure this is not your fault but the server admins’. They did not install many server modules by default. I would like to tell them wich modules are needed to get it working again. Is there a list of module dependencies somewhere?

Sorry to bug you with my poor server configuration.
