W're moving our MU install from a Media Temple GS server to a DV server. We've moved the content, created the new database, and logged into the database from both phpMyAdmin and the command line. WordPress tells us "Error establishing database connection" though.
I've checked spelling and code errors.
I've made sure the database is accessable with that connect info.
I've "repaired tables" in mysql.
I've removed all plugins.
What could make it not connect?
