Hi, David. I had set it up a few months ago using your instructional video, and it worked perfectly until the last update. I had tried resetting the path to the configuration file, even though it appeared to be correct, before I reported the problem. I haven’t touched it since except to verify.
Yes, in answer to your earlier question, it occurred when someone clicked to initiate the payment. I think I mentioned the line numbers referenced in the error message. When I looked to check it out, that line appears to be referencing the configuration file but I’m not a PHP person, so I wasn’t sure whether it was something else.
Thanks!
