Once again, cheers for the help, kmessinger!
I guess I do have access to the privileges then. But granting them all to myself doesn't seem to help trying to access wordpress.
I do have access to the database, and I have created a new aministrator account in the wp_user table and the metuser table.
But it's still not possible to access the dashboard (I still get the 'You do not have sufficient permissions to access this page.' message).
I was told by the previous developer that this is because the database is set to readonly.
So any idea how to change this setting? Is it just a matter of finding a directory and changing chmod, or is it something I have to do in phpadmin?
Apologies if this is confusing. Your help is really appreciated.
