database could not be selected.
httpelit_elite
have permission to use the httpeliteprintso_eliteau_ELITEPRINTMAINDATABASE
database?username_httpeliteprintso_eliteau_ELITEPRINTMAINDATABASE
. 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.
