"The database connection failed. Please check your database configuration in include/db/config.php. If the configuration is okay, check if the database server is running."

I don't know either; I just got that too. Eric K said that he was checking with the ISP and looking into it.

It means they're closing in.....they've been taking lessons from the Scientologists......

I've gotten that one as well as some variation of this:

Phorum Database Error

Sorry, a Phorum database error occurred.
Please try again later!

Error:

Lost connection to MySQL server during query (2013): SELECT * FROM phorum_messages WHERE forum_id = 2 AND thread = 1550232 AND status =2 ORDER BY message_id

It's not your problem. It's a server problem.
