I am a new user.
I had a quiz set up and working successfully. I needed to edit some setting but today this came up with an exception error. This has not happened before.
As I couldn't fix it or understand it, I deleted the quiz and tried to add a new quiz. I am getting the same exception error.
I have absolutely no idea what to do. Any advice would be very gratefully received. I am using Moodle 2.6 which is held on a hosted linux server
