I tried adding a product with only a regular price to Virtue and the price and add-to-cart button showed up fine. I see that you also don’t have an add-to-cart button. Virtue is popular, well supported and regularly updated. If it was bust there would be a lot of noise and there are no recent reports of this problem on the virtue support forum. Try the default theme, if that fixes the problem than maybe it is a Virtue issue but I suspect the cause lies elsewhere.
Consider leaving the other plugins deactivated until this is solved. Sometimes even deactivated plugins can have an effect. Try renaming the plugins folder to completely deactivate them.
Your site is showing 12 console errors from something called testjava.js. Maybe not relevant but not a good sign.
If the problem persists with just WP, WC & the default theme in the loop then your install may be corrupted and a reinstall may be called for.
