I didn’t know this until now, but I’ve checked and its true on my site, if all the variations are the same price, then the default behaviour is that the price between the drop-down and the stock quantity doesn’t show. You can test this by altering the price of one of the variations on a product whose price doesn’t show. It should now show.
On other themes, there is a price or price-range between the product title and the short description, but your theme does not show this. You can test this by trying the default theme – does the price now show above the short description?
The author of this site:
https://phele.com/woocommerce-display-price-variable-product-variations-prices/
has kindly provided some code to go in functions.php to alter the default behaviour of WooCommerce so that it does show the price under the drop-down when the variations are the same price.
The caveat is that it needs php 5.3 on the server, on 5.2.17 it does not work according to one comment, so I can’t test it. Hopefully your mileage may be better.
If this code doesn’t work, you will need to either add a few cents to one of the variations to make the prices different, or delve into the page template so the price does show above the short summary. PHP skills will be needed for that.
