The product price disapears

[dimarini]

Hello,

I am developing a website using a template with J1.7 and VM2. The domain name is http://lotos-u.com/. A very strange problem appeared.
When the site is offline the price of a products is displayed as presented on fig1.
When the site is switched to be shown on the web than somehow in a meantime the price in question disappears, see fig2. Switching on and off the site restores for a certain time the product  price display. Than the same thing happened. The browser is latest Mozilla Firefox.
Have somebody an idea what is happening?

Thank you and Best Regards!

do you choose to show products to "anonomous" shopper group?

Configuration >> Pricing >> Final Salesprice should be checked for show price!
Now everything is ok!
