We've rolled out version 6.08 of Virtualmin virtual-server module. This release includes some security fixes (domain owners can obtain access they shouldn't have), so upgrading ASAP is recommended.
Changes since 6.07:
The Dropbox fix also needs a Webmin update to 1.932 (also rolled out today). The updated MariaDB 10.x support means we can finally support Debian 10 and CentOS 8. Debian 10 support should be announced in a day or two (we're testing and it looks good so far), and CentOS 8 soon after.
As always, report bugs!
