I worked on this installation of v2.4.6 for a few months when I bought it, then put it aside without ever going live. A while back there was a hard disk crash and all of the files were moved to another volume and directory. Recently I decided to revive the project. When I try to access store.php, I get a page of errors like this:

Code:

Fatal error: Call to undefined function sc_get_config() in /Users/Shared/www/steelguitarshopper.com/squirrelcart/pre_common.php on line 247
Seems that maybe the scripts aren't finding all of the PHP code or something. Suggestions on how to fix this would be appreciated.

This is an Apple Xserve that runs multiple web sites, btw. I have direct access to the machine - it's in my office.
