The Roundcube WebMail system included in cPanel has been updated in Spring 2021. The user interface (UI) is now mobile-responsive so it is usable on small mobile screens.
Many people will prefer this newer and more modern UI, others may prefer the classic old style which has been in use for years. The good news is, if you prefer the old style, it's easy to switch back!
To switch back to the classic old style of UI in Roundcube:
- With Roundcube open, click on "Settings" in the menu.
- Click on "Preferences", then click "User Interface".
- Change the "Interface Skin" to "Larry" – that's the old UI. ("Elastic" is the new one.)
