Error establishing a database connection! This probably means that the connection information in youn wp-config.php file is incorrect. Double check it and try again.
Are you sure you have the correct user/password?
Are you sure that you have typed the correct hostname?
Are you sure that the database server is running?
WTF?!?! I haven't changed anything and this error came out of nowhere. I went in and checked my database and everything is okay.
