A couple of my clients customers have had problems checking out:
"I get all the way to the checkout, enter my email and password .. but when I hit 'Submit Order' it takes me back to the top of the page saying 'Please enter an email address' ... but it's already there. "
Do you have any pointers as to what could be happening? I first heard of this issue cropping up on 3rd March.
Is there any chance it could be linked to the custom code fix for the flickering login Safari issue? I have not yet removed the custom snippet fix.
