Hi! I'm having some issues on my site, the Cron job is not running properly
I'm currently running Moodle 3.3.2 (Build: 20170911)
Whenever the Cron tries to run (o I try to run it) it gets stuck at (core\task\legacy_plugin_cron_task)
Here's an output I copied when I tried to run it
Server Time: Sat, 21 Nov 2020 23:54:22 -0400 Execute scheduled task: Procesamiento heredado de extensiones (core\task\legacy_plugin_cron_task) ... started 23:54:22. Current memory use 7MB. Running auth crons if required... Running enrol crons if required... Starting activity modules Processing module function quiz_cron ... Looking for quiz overdue quiz attempts... Notice: Undefined offset: 6 in /home/cedetahucom/public_html/cedetahu-virtual/question/type/gapselect/questionbase.php on line 129 Notice: Undefined index: in /home/cedetahucom/public_html/cedetahu-virtual/question/type/gapselect/questionbase.php on line 130 Fatal error: Call to a member function summarise() on null in /home/cedetahucom/public_html/cedetahu-virtual/question/type/ddimageortext/questionbase.php on line 65I purged all caches, tried to run scheduled tasks individually, and some of them ran, but whenever the Cron tries to run, it fails at the afore mentioned point.
Upgrading to a newer version of Moodle is not an option I currently coul afford, as the site is (highly) active and running several courses
I hope you help me to solve this issue.
Thanks in advance.
