Is there any way that the default quantity is 1 rather than 0 (as it is now) in the section to buy tickets? If the user clicks Add to Cart without changing this number, the cart is empty and the user is redirected to go back to the Shop (of which there isn’t one). Ideally would like a functions.php solution so I don’t have to edit the core plugin file. I have tried using something that defaults Woocommerce quantity to 1, but there must be something in your plugin that is overriding it. I don’t have different tiers of pricing for each event, so defaulting to 1 is ideal.
I found this thread, but it’s for the old Woocommerce plugin https://theeventscalendar.com/support/forums/topic/checkout-quantity-field-is-zero-can-it-default-to-1/
