Error [Xoops]: Unable to connect to database in file class/database/databasefactory.php line 34
Check your database settings in mainfile.php
These must match database access settings on your server.
Make sure your database name has the correct and full name; ie if you created a database called "xoops2" many hosts require the full name to be inputted to access this database, so the name will be "something_xoops2" "Something" is often your host account user name used as a prefix.
