How to get back to previous version of Webmail

[Merluche]

Hello,
I'm using Roundcube Webmail as my professional email. This morning I'm opening it and I do not see or understand anything. This is the same UI as riseup, and I do not find it friendly at all. Is it possible to get back to the previous version? My priority when I open it is to have an overview of the object of the mail. Now I only see the begining of it and the content it a window on the right that I cannot reduce or close.
It's really no handy for me.
Thanks for your help.

Roundcube is not a service it as a piece of open source software your email provider is using to give you webmail. You might be able to switch to an alternative skin by going to Settings > Preferences > User Interface > Interface skin. Or it could be this is the only skin your provider allows. Please contact your email provider directly for support.
