Fatal error: Call to a member function asXml() on a non-object in
Hi Coding gurus,
I have downloaded a script to work with Worldpay to show how to make direct payments, After making a few modifications of my own I realised it does not actually work I get the error:
ERROR: "Fatal error: Call to a member function asXml() on a non-object in \WPDirect\WPDirect.php on line 889"
There is a few pages so I have attached the one which causes the problem, please let me know if you need any more to help me solve the problem, I have tried printing information to get to the bottom but I am not having much luck!!
