dear moodler,
i am using moodle 3.5 and I used to run cron file automatically in the control panel. i set the log record of 120 days from the current day to previous. log data is working fine but i noticed that my forum messages, result of quizzes are not deleted. my moodle is containing the record of all forum messages and quizzes from the last year also. please help me how can i delete the forum and quizzed data from the moodle to get the optimized performance of the site.
