Horde support will be removed from cPanel and WHM starting with version 108. This is because Horde does not support PHP version 8 and PHP version 7.4 will reach end of life in November 2022.
Horde is based on PHP version 7.4 and will no longer be available after this date, which is why Horde will be removed.
What does this mean for Heberjahiz customers using Horde?
cPanel Webmail will be Roundcube focused in the future. Your messaging will be available in Roundcube as it is in Horde today.
What should I do to prepare for this?
Nothing. When updating cPanel & WHM to version 108, the system will automatically migrate all Horde data to Roundcube.
