Call to undefined function course_get_format()

[maxCSA]

Hi,

Since a couple of days, or maybe weeks, I have this error when running the scheduled task :

Execute scheduled task: Tâche crom de réengagement (mod_reengagement\task\cron_task)
... started 15:03:42. Current memory use 12.7Mo.
... used 30 dbqueries
... used 0.66566801071167 seconds
Scheduled task failed: Tâche crom de réengagement (mod_reengagement\task\cron_task),Call to undefined function course_get_format()

I tried to purge cache, without success.

I run Moodle 3.9

Any idea?

Thanks

I finally found that it is a conflict with another plugin
