error with child products after update to 2.0.22a

[tope]

hello,
I upgraded from 2.0.22b to 2.0.22a virtuemart and I have errors in the products shown on the front-end.
There are products in which the child products are shown correctly, there are products in which the child products are not shown, and there are products which are child products shown derivatives product of other items.
Can anyone help? I searched the forum and have not found anything about it. All products are ok in the back-end, the problem is only in the front-end.
Thank you.

This sounds really crazy. I think to understand this, I need access to phpmyadmin or similar. Extplorer or similar and in generel BE superadmin access.
The only reason this can happen is a problem in the hash of the cache.
