We have been running Moodle 3.5.3 since August with no issues. Just before Christmas I set up a quiz and got the error Exception - syntax error, unexpected end of file, expecting ',' or ';' when I tried to test the quiz after changing one option but I dont remember which one. I set it back to default and the error went away. Those quizzes have been done now by 250 people with no problems.
Today I went to add another simple 10 question quiz and when I attempt to test the quiz I get the error Exception - syntax error, unexpected end of file, expecting ',' or ';'. This happens in any course I try to add a quiz to.
I have a test site running 3.5.3 that was set up the same day on the same server. There are no issues adding a quiz to that site. Nothing has been touched on either site since before Christmas.
Any advice is appreciated.
