This module is quite an old one and is similar to others I have tried lately in that they don't communicate with the database fully. This particular one shows in admin but the main tables have not been inserted into the database. Even with manual insertion the module doesn't send any data. I don't think there is much wrong here really but the method of communicating with the database must be different from earlier xoops versions. Where would I start to try and fix this particular module? If I can fix this one I can probably fix others.

You might turn XOOPS debug on so you can see if there are any issues either with PHP or if something shows in the SQL Query logs.

I quickly looked at the module (version 0.21 from the module repository) and it has additional issues that aren't really XOOPS related. For example, the module still attempts to use the $HTTP_ which has been deprecated since PHP 4.1.
