Hello dear, having issue in joomla 3+ with virtuemart price display on your theme? there is having many thing to does’t show price or other product data.
You have issue from oneof below option:
Option 1: Check template/theme virtualmart overriding version and current version is same or not.
Goto > template > themename > html if exist com_virtumart then rename it and see. If appear then you have issue in component overriding
