Writing to the database is not needed, it will cause PHP warnings and errors, but the site will work. Anyway, this is not real problem, I can say to the customer: "ey, this is a demo CD, for this stuff to work you need a real server, not a CD".
The real problem is the Apache server.
Come on, people, help me and I'll release a "ready to run in a CD XOOPS distribution" for everyone.
