I noticed that in my Cache configuration under Site Administration->Plugins->Cache->Configuration,
I have the following:
I don't have a folder named default_session or default_request. I only have default_application located in the moodledata/cache/cachestore_file directory. Does this cause an issue since the coursecat is mapped to default_session and it does not exists? So if I mapped coursecat to default_application, would this cause issues elsewhere?
Another issue is that I have given default_application 777 permissions so that error will not appear when I purge caches. It works fine, but then the permissions change back to 750 on that folder. I have changed the $CFG->directorypermissions = 0755 in the config.php file, so why is it reverting back to 750?
