Adding coupon has made the Admin Menu disappear
I added a coupon today and wanted to just have a discount on one product but when I selected the option it took me to a 404 page with this link: /Admin/products_Search.php?InProcess=AddToCoupon
I changed the lower case 'p' to upper case and then the link worked but after that the entire menu system is not working in Admin and if I type in a direct link to page I know exists eg /Admin/Products_Search.php it works incorrectly - every product has the 'add to coupon option' and none of the other Admin fuctions are available.
I deleted the coupon and I also restored my database to a save before I changed this and it still is not working and has the same errors.
This is on Powerstore 3.
We are adding many products everyday at the moment so it is very important it gets fixed as fast as possible. Thanks for your help.
