I loose products in categories

[euge001]

Virtuemart 2.0.2, everything were good till today. When I opened category link on website menu I found that the category page is blank now.
If I open link to product(s) page directly I can see the product(s), but not products list in category. So my products are on place.
I re-created menu link to category and then even re-created the category itself but it doesn't help me to fix the problem.
Please help me to fix it!
Thank you.

Are the products assigned to a shopper group?
