MySQL server has gone away

Cannot select database

The database server could be connected to (which means your username and password is okay) but the db100046536 database could not be selected.

• Are you sure it exists?
• Does the user db100046536 have permission to use the db100046536 database?
• On some systems the name of your database is prefixed with your username, so it would be like username_db100046536. 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.
