Error reconnecting to the database

This means that we lost contact with the database server at localhost. This could mean your host’s database server is down.

Are you sure that the database server is running?
Are you sure that the database server is not under particularly heavy load?

If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.
