[digiKam-users] Can't open DK - DB-Error external DB-Server

[cool.chris65 at web.de]

Hi,

since today I can't start DK AppImage 6.0.0 (Last build) because it reports an 
error "You have not the permission to alter table" ... (or similar text - it 
is always in german ...

Here is the console-output:

This problem starts after trouble with dk and killing it from desktop.
the server is mariadb 10.0 on debian8, dk is running on a kubuntu 18.04-64 
desktop

Hope you can help
Thx
