Having issues editing/saving my opencart 2 orders. When I try it either gives me a JSON error: "SyntaxError: JSON Parse error: Unrecognized token '<' OK" Or it tells me on the last 5th page of editing orders: "Warning: No Payment options are available!" and even though I selected the payment it still thinks there is no payment method selected. ONLY WAY TO EDIT AND SAVE: Only if I go fast through the first 4 pages so go, CONTINUE, CONTINUE, CONTINUE, CONTINUE, than on 5th page I have to fast click refresh SHIPPING METHOD, fast refresh PAYMENT METHOD, and click SAVE, only this way I can be successful in saving. What could be causing this? Any advice is much much appreciated. I can't really figure out when this issue started but I know I've had it for the last year or so. Its really annoying having to go to my cpanel and database every time I want to edit an order.
