Maybe making a full structure+content database backup of the modules your using, except the system module which seems crazy, dumping the database, doing the reinstall of xoops, putting in your mainfile with the correct details, and restoring the backup of the modules your using.

This would be a rather more complicated process which should be done with much care. Don't pay me much attention... this is just an experimental solution and if not done correctly very risky to lose information you already had.

You could proceed to the following test.

1) Create a new directory on your server.

2) Make a fresh installation of a standard Xoops.

3) See how it behaves.... If it works, the problem comes from your site. If not, the problem may comes from your server configuration.

4) Install your modules one by one, and see which one causes troubles...
