Very new to CS-Cart and im not a very savvy front end guy. (Heads up). I imported all of our old clients from the old site (not CS-Cart) into cs-cart via the DB. Now occaisionally I get an older client that logs in, places his order and when he tried to complete his checkout he gets hit with a 500 “Service Unavailable” error. This has been happening more frequently and I cant figure out what the issue is. When I view Source on the error page, im always getting this error… and I hav eno idea what it means… or how to fix it. Any help would be greatly appreciated.
