Free product can’t be added to the cart. I see message “Sorry, this product cannot be purchased.”
WooCommerce verifies product before adding to the cart. So this product must be published, in stock and has price defined.
How can I hide original prices?
It’s a PRO feature. You should turn off option “Show striked prices” at tab Settings, for category and product pages.
When loading products on the page using the “Show more” button, the discount on products is not displayed
The “Show more” button sends ajax request. Please, visit “WooCommerce” – “Pricing rules” – “Settings” – “System” and mark “Apply pricing rules to backend orders”.
The discount badge on variation products is not displayed
Please, visit “Pricing rules” – “Settings” – “Calculations”, mark “Calculate “On Sale” badge for variable products”. It’s a PRO feature.
How can I increase prices in my store?
A negative discount should be used.
