Site's Down After Move!!

While moving our newly created site from the subdomain it was created on to its actual home, I received the following error below. I used FileZilla to create a backup then move the files to the new home. However, both the old location http:https://www.review3.shopabgifts.com and the new location - https://www.shopabgifts.com give this same error. The file it mentions is there, so I can't figure out what is causing the error.

Anyone have any ideas? we're using 1.3.7. I'm sure I missed something, but can't figure out where the problems are.

Thank YOU

Yes, you need to make sure that you have removed any instance os the subdomain name located in the includes/configure.php and admin/includes/configure.php

Hi Merlin -
I had already removed all mentions of the review subdomain in both config files, with the exception of the navigation to the database directory, as I thought it would be fine there without moving it. I also updated the sessions file at the time.

Since neither store site was working, I removed the files from the new location and downloaded a fresh copy of ZC with the hope of pointing it to the database. But I've unfortunately hit a snag there too, as it doesn't see the DB, which is still active on the admin panel of the https://www.review3.shopabgifts.com/admin subdomain.

I know that making this move is the right thing to do for the store, but I've been dreading doing it. Sorry that I'm throwing a lot at you, hopefully you're wisdom and experience will be able to point out where(or rather how many times) I screwed and how I can fix it. THANK YOU!:frusty::censored:
