We have a certain course which is getting these errors on certain quizzes:
"Can not find data record in database table context."
The resulting page is also incomplete, it is missing the header on the HTML page.
Turning on debugging, these are the error message that we get:
Quiz A, attempting quiz:
Debug info: SELECT * FROM {context} WHERE id = ?
