[Solved] I can't access the Admin Panel
Apparently everything went well during the installation, without errors, the Carbonio Admin Panel and Webmail Login screen load without problem, but unfortunately it does not accept the "zextras" user credentials.
Is there any possibility to recover the password or create users again?
You need to change the password for the zextras user before accessing the web interface. See https://docs.zextras.com/carbonio-ce/html/multi-server-installation.html#post-installation-tasks
This information for some reasons has disappeared from the single server. I will fix it ASAP, together with the other reported today. Thank you for pointing this out.
Thanks, it worked perfectly.
Now I'm going to study to put it into production.
