Hello,
for this, will a script appear and we run it automatically or does Roundcube have to be updated manually?
I find the update steps on the forum??, I don't want to break anything on the server, I'm new to the forum, and a KeyHelp user, after 9 years of CWP Panel.

THX!

This will be included w/ the upcoming panel update; it is just an informational note. The developer will address it as soon as possible.
Do not update RC by yourself unless you know exactly what to do.

I appreciate the promptness with which you responded to the requests, we are waiting for the automatic update from KeyHelp.

Thanks, but I'm not part of the support team
You'd be better off thanking the Developer and the Keyhelp Team.
