The database server could be connected to (which means your username and password is okay) but the
darenmvr_forsherupdated database could not be selected.
darenmvr_forshehave permission to use the
username_darenmvr_forsherupdated. Could that be the problem?
If you do not know how to set up a database you should contact your host. If all else fails you may find help at the WordPress support forums.
