Upgrading from XOOPS 2.3.1 or 2.3.2 (easy way)
1. Get the right update package from the sourceforge file repository
2. Overwrite your existing files with the new ones
3. Move the "upgrade" folder inside the "htdocs" folder (it's been kept out as it's not needed for full installs) on your local machine
4. Access /upgrade/ with a browser, and follow the instructions
5. Follow the instructions to update your database
6. Delete the upgrade folder from your server
7. Update the "system" module from the modules administration interface, other modules, especially "profile" are recommended to update as well
