Warning: mysql_connect()

I'm putting together a store for a client - I uploaded items about a few weeks ago, and everything was wonderful until I checked it out today ready to sort out the postage to find text on the page (hidden has been used to replace file names):

Can you please tell me what I need to do?

With thanks

Check the settings in config.php and mysql user permission.
