Since our upgrade from 3.7.1 to 3.9.1 teachers had mentioned that sections in a course sometimes 'disappear'. Usually I do not believe them and it always seems to be user error.
However, I have seen some strange things in the log-files of a course:
Course modules are deleted from Command Line Interface (cli) without an IP address. These are regular teachers, 100% only using the web-interface of Moodle. No CLI.
Can anyone explain what these logfiles mean and how can it be that Course modules are deleted using CLI?
Can I still find the mentioned module ID's in the database or Moodle temp? I want to know what is disappearing here.
