wrong number of products shown in backend

[TheotV]

Hi all,

We seem to have a bit of a problem. It is that in the Prestashop backend our catalog shows the wrong number of products. We were using the product combination generator of Prestashop and have generated several products with about 1400 combinations. We have decided to handle this differently so I decided to delete all the product combinations in the backend.
Deleting the product combinations was not too much of a problem, but to my surprise the catalog in the backend still shows the number of products that corresponding with the generated product combinations. Although they do not exist in the database anymore.

This is very confusing when administering the product catalog. Does anybody know how this number is calculated in the backend? I thought it was calculated using the number of combinations in the tables ps_product_attribute_combination and ps_product_attribute, but that somehow does not seem to be the case.

Can anybody help me out?

By the way: we are using Prestashop 1.2.5.0 and are not wanting to upgrade yet.

Hope to hear from you.

Kind regards,
Theo
