is it possible to truncate the oc_activity table in the mysql database without any adverse effects?
I've tried to do that with the 'activity_expire_days' entry in the config.php and set it to one day. But since three days (since upgrade to 9.0.4) the activities are not cleaned as defined. There is a webcron that runs fine every 15 minutes. That shouldn't be the problem.
Is there any other way to get rid of all old activities? Is it that easy to do that by empty the oc_activity table or is there anything else to consider?
Thank you in advance for your support!
