I have noticed a strange issue recently on the Magento checkout. The same thing occurs whether I am using the default onpage Magento checkout, or if I am using the lotusbreath onepage checkout extension.
When I go to the checkout, there is a credit card form, in place of where you would usually have a list of payment methods (PayPal, Pay In Store, Sage Pay etc.). I can not see these other options now.
When I load the page, I do see them load, very briefly, but they are immediatley replaced by this form. I have disabled all payment methods, apart from pay in store, sag pay and paypal. Sage pay takes the user to their website to process payments, so the form does not belong to that.
Where could this come from?
