Opencart version 18.104.22.168.
We recently had a user submit an order with a mistake in their email address: name@domain,com with a comma instead of a period before com. Is there any way to validate the format of the email address before it is submitted?
In catalog/controller/checkout/register.php and guest.php file, there's a validation process with the email structure that should be integrated already. If not, on more OC versions, this option is available. You can also try alternate ways to validate new emails upon registration process by downloading an extension from the Marketplace.
In addition, since you're using Journal 2. Journal version has increased to its 3rd release. See by contacting their support staff if the enquiry you are reporting about can be solved by using their extension.
