I just installed roundcube on a raspberry pi4 (raspbian) from the package that they provide ( 1.4.3 ). This is also running pihole and uses lighttpd as the web server. Receiving email works fine. But when I click the Compose icon a linux file manager window opens up that shows my Desktop prompting me to save "blank.gif". I can either save it or cancel out of that window and then I'm back to the roundcube composing screen. Also, during installation I chose sqlite as the database in ~/roundcube. Also: I use the Brave Browser to access roundcube from another machine on my LAN.
I was looking in the sqlite datebase:system table:
roundcube-version 2016112200
Does that mean that I am running a 2016 version?
Why is this happening?
