'!'); I'm not sure whether this is anything with the VQMD or EVE extension. How to fix this? Steps to try: Check if you have a eway.php in the list / controller / payment folder Verify the square name of that file: Class Controller Payment and Controller { . Check file permissions. It's a good day!
