In Administration
Configuration
My Store
I find duplicate categories with different values.

The first installation of osC was 10/04/2004 after populating the store with products, all the images disappeared, even adding the images again, they did not show up. I was ready to give up.

But after tax time
I decided to try again and updated to osC 2.2 on 5/5/2005 was able to upload the images after reading in the manual that the chmod on the image file had to be 777.
The store started to look fine.

I don't remember what I did but now I can not access the http:www.super2000.com/catalog

I get these errore messages.
Warning: main(includes/classes/shopping_cart.php): failed to open stream: No such file or directory in /home/httpd/vhosts/super2000.com/httpdocs/catalog/includes/application_top.php on line 123

Fatal error: main(): Failed opening required 'includes/classes/shopping_cart.php' (include_path='.:/usr/share/pear') in /home/httpd/vhosts/mystore/httpdocs/catalog/includes/application_top.php on line 123

Line 123 in catalog/includes/application_top.php seems to be:
require(DIR_WS_CLASSES . 'shopping_cart.php');



What would be the best thing, delete the installation? and reinstall.
If I delete the installation can the database be saved?
