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 wordpress database could not be selected.
- Are you sure it exists?
- Does the user
root have permission to use the wordpress database?
- 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 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.
