Correct prices don't show, all prices = 0?!

Hi! I can't understand what the problem is. In my categories and products in the admin section I see all correct prices. But when I open menu "prices" in the store section of admin, all prices are zero. The same thing is happening when I open my store, - the prices are zero.

I am using dual prices module. Maybe that is the reason? Although I have used it before, and nothing like that ever happened. Can anybody help me solve the problem?

Thank you very much, I've read the posts, and checked my currency settings. The value for my currency was set to "0". I've changed it to "1", and that solve the problem!

FYI ... found this by searching for "prices zero" in the FAQ area: https://www.zen-cart.com/tutorials/index.php?article=96
