  • 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.

Hi,

Sometimes when I try to log in to Plesk over the web I get:

Code: 
Internal error
Error: ERROR: UnknownError: boost::interprocess::bad_alloc (Hierarchical.php:201)

and I'm unable to log in. What's causing it and how to fix it? I tried restarting Plesk but it's still the same.
