Hi there, So when my customers are about to purchase something, after registering and clicking Compete order, when they select the payment method (PayPal) and selecting it, they click Complete Order and it takes them to this page https://gyazo.com/44f5e1034982a0a042ef650e72c4cf4e Can anyone please try and help me. I have done multiple installs of WHMCS and Ive had multiple errors. And since i bought a license off another provider (Unlimited Web Host) I can't find out if its there files or mine which has the problem. But any fix would be helpful! Many Thanks, Callum
