Whaaaaat?…. you have to be more specific than that….Please
Can’t select database
We were able to connect to the database server (which means your username and password is okay) but not able to select the altherit_wordpress database.
Are you sure it exists?
On some systems the name of your database is prefixed with your username, so it would be like username_wordpress. Could that be the problem?
If you continue to have connection problems you should contact your host. If all else fails you may find help at the WordPress Support Forums.
Are you sure that that’s the name of your database? Try checking it in your server’s control panel.
