I tried in various ways, updating plugins, removing all unnecessary ones, made all the settings for Woocommerce and products, but I didn’t achieve any success. I activated shipping and the payment system.
Note: I’ve been working with Woocommerce for many years, with other themes, and I’ve never had this type of issue.
Thanks for choosing our product!
Please note in the latest version of Dokan Multi vendor plugin, it prevent store owner buy their own product.
So you need to log out or use incognito mode of the browser to check add to cart function.
If you don’t use Dokan you can deactivate this plugin.
Here is the document of the theme: https://document.harutheme.com/pricom/
Hope this helps!
