When I change the role to "Student" to view the lesson,
there is the error message as following.
Error: could not find lesson_timer records
- line 476 of \lib\setuplib.php: moodle_exception thrown
- line 1219 of \mod\lesson\locallib.php: call to print_error()
- line 297 of \mod\lesson\view.php: call to lesson->update_timer()
I have search on the moodle and find one article:
https://moodle.org/mod/forum/discuss.php?d=165375
and read the links in it. But the links are in 2007 and the
codes are very different in the version I used: v2.5. I really
have no idea how this error happens. Any clue is very welcome!
Thank you in advance!
