Are you seeing a blank white screen while running shop.php or admin.php or errors on screen?
The blank screen means PHP has thrown an error. To see the error message on screen, place an empty text file called aom_debug.txt in the same location as shop.php. The presence of this file turns on error reporting for both your shop.php and admin.php files.
If you are unable to fix the error displayed, please send us the following:
1. The error message(s) you are seeing
2. Your version of PHP (4 or 5)
3. A screenshot if applicable
4. Also download and attach your saved settings file /aom/cfg.saved.php to the email
