Hello Sir,
I tried peer reviewing the code for bulk deletion (https://github.com/timhunt/moodle/tree/MDL-48771) by following the instructions in Moodle Docs - Peer reviewing someone else's code.
I was not able to delete the selected questions.
It gave the following error after the confirm pop-up shows up:
"Coding error detected, it must be fixed by a programmer: PHP catchable fatal error"!
