The site that i'm working on is http://www.perfectbrewingsupply.com. The site seems to come up properly (after i reset a new user/pw in the config file) but when trying to access the database for zencart, i am still receiving the following error:

0 DB_ERROR_NOT_CONNECTED
in:
[select * from project_version WHERE project_version_key = 'Zen-Cart Database' ]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

I have a feeling (though not sure if this is the case) that it has to do with the database user. There's one user in there but i can't seem to update the password. I created a new user/pw, updated the config file and the site came back up. However, still cant log into the backend, get the error above.

Any ideas or suggestions?

Greatly appreciated!
