I am using BS Authorize plugin (/) as a payment gateway in woocommerce which allows payment using credit card, Echeck and paypal. It works fine for logged-in user but for logged out user on checkout page, when clicking on Place order button after entering information, it hangs and do not proceeds the order (stays on same place). It gives following error on Chrome Developer console "Failed to load resource: the server responded with a status of 400 ()" https://site/wp-admin/admin-ajax.php. What could be the issue? Same issue occurred to a person and he asked for solution to their support and I saw no reply. /
