Since updating to the latest stable Webmin release user and group quotas are not being displayed within Virtualmin nor do I receive the daily emails if domains exceed their respective quota limit. The last message delivered was Saturday which was the day I updated Webmin.
I've gone to Webmin > System > Disk Quotas to check that quotas are enabled for users and groups (they are). I even click on the filesystem and check quota which completed after some time successfully.
However when I go to Virtualmin > System Settings > Re-Check Configuration I get a message that "Quotas are not enabled on the filesystem / which contains home directories under /home and email files under /home. Quota editing has been disabled."
