I am trying to upgrade my Moodle 1.9 to 2.2 and I keep getting a database connection error. I have checked with my server administrator for the correct host, user and password and it is still not working. I have no idea how to locate the config.php file to make any changes to it and I am completely stumped. MySQL server. Can someone please advise? The error I keep getting reads:
Error: Database connection failed
It is possible that the database is overloaded or otherwise not running properly.
The site administrator should also check that the database details have been correctly specified in config.php
