Customer Group Option Pricing

Hello OC!

I'm running an ecommerce portal in which I used 3 types of customer groups. In the products option page i have the ability to add different prices to different customer groups. Yesterday I got a parse error and then on suggestion of some one I deleted all the files exists in vamod > vqcache folder. Now I cant able to fadd different prices to different customer groups for the products haveing option prices. Can any one suggest me how to re enable it on product options page. Thanks in advance

What OC version?
What extensions?
Why can't you add prices any more - is an input missing etc.?

Previously the Dropdown menu in the options page of a product which allows to add a price to different customer groups. But after deleting all the files form vqmod > vqcache (in order to fix an fatal php error) the Dropdown menu of customerg groups disappears. Hope you understand and request you to please help me

Sorry to inform you that the Customer Group wise pricing was displayed earlier with an extension called "Product Option Discount" which was deleted some days ago and now installed the extension yesterday and now I cant able to get the previous settings of that extension.

Can some one help me in retrieving the previous settings of that extension

This is a very specific request and what you really need is a developer who knows what they're doing to have a look at the extension and see if it has left the database table after it was removed. So I suggest you post on the Commercial Support Forum to find someone who can help you.
