Please provide a valid email address.

Hi!

Since I sell virtual products, I have removed almost all the billing fields on my checkout page (https://testsidene.com/shop/?add-to-cart=15983), but I get the error: “Please provide a valid email address.” But I have removed the email field, so there is nothing to provide (I removed the fields by following the instruction here: https://www.wpmayor.com/how-to-remove-the-billing-details-from-woocommerce-checkout/). And even if I bring back the email field, I get the same error. Have you any ideas?

Thanks ??

Overrides: Your theme has a woocommerce.php file
you will not be able to override the woocommerce/archive-product.php custom template since woocommerce.php has priority over archive-product.php. This is intended to prevent display issues.
