I hadn't checked roundcube out in a while so nothing on what config I changed recently.
Removed and reinstalled to version 1.3.17 which is the latest version on Rasbian Buster.
What can I check? How to turn on debugging logs?
Regular mail server & clients are otherwise working fine.
Thanks!
Whats the problem? I guess you are getting an error when you try and login but what error? Anything in the Roundcube error log (default location [rc root]/logs/errors)? If you are getting a connection error or something like that and there is nothing in the logs dir then you probably php can write to that folder.
