When you edit the product page: If there is no ‘general’ tab for price when ‘variable product’ is selected, try this troubleshooting.
Does your ‘Price’/’General Product’ info tab flash and then disappear when you try to edit your WooCommerce product? If so, your store isn’t showing prices and you have no way to enter prices for your item, but there’s an easy fix.
The solution is simple.
You probably have your product accidentally listed as a variable product. Just switch it to a Simple product and that should solve the problem!
