  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

CentOS 8 support

I had some weird firewall problems on CentOS 8 and Obsidian (like users being banned for no reason - wrong detection). I didn't had time to investigate further but something was definitely off. I will post here once when i find time.
 
Update: Before i continue i want to clarify that i am speaking about CentOS 8 and Obsidian.

By reading log files for now i am pretty sure Web Firewall is doing problems on wordpress installations. It is triggering false positives and making some plugins unusable so whole websites can be broken. But we knew that already. Obsidian staff warned us about this in release note.

I'll see myself can i tweak it.

So until further development is made: in case you are getting wordpress errors on CentOS 8.1 and Obsidian (it depend on theme and plugins used), websites not working and so on. Try to see your Fail2Ban IP list - it is very possible you are added to the Jails and being banned.

Also set up ModSecurity to detection only and monitor your logs.

As soon as i unban myself and switch to Detection only - all wordpress websites are running normal. Try using Wordfence instead. Just make sure to completely turn off their LIVE TRAFFIC feature and set it to low resource scanning.

Actually that was funny if it was under spirit of a friendly joke :)
