Suddenly WordPress can't find my database.
The config info is correct and the database is not down. I know because Moveable Type is in the same database and that works fine.
I know that my Web host recently changed the PHP version on the server, and POST data is no longer extracted automatically, but this has nothing to do with POST data. What's wrong here?
I tried upgrading to the most recent version of WordPress, but it still doesn't work.
