If you receive a Database Upgrade Failed error during the Installation / Upgrade script process, use this topic as a guide to report the problem and get back up and running. A generic error is shown below to demonstrate what a database upgrade failure may look like:

- Locate the error message seen in red (as in the example above). Select that text, and copy it to your clipboard.
- Open a helpdesk ticket with our support staff, and paste the error message into the ticket. Information on our helpdesk can be found on our support page: http://www.squirrelcart.com/support.php
- After submitting your support request, click the Restore From Backup button. You should see a page similar to the following:
- Click the filename corresponding to your backup. You should then see something like this:
- Your database is now back to the way it was prior to the upgrade. If you need to get your store back up and running immediately:
- Rename the squirrelcart folder to squirrelcartNEW
- Rename your squirrelcartOLD folder to squirrelcart
- Rename the sc_install folder to sc_installOLD
- If you uploaded new versions of store.php and home.php, rename those to store.php.NEW and home.php.NEW, and restore your backup copies of these files.
After this, your store should be back to it's pre-upgrade state. Leave the folders in place so that you can continue your upgrade again without having to upload new files.
