Akonadi & Co

must admit I am getting scared to do updates!

After battling to get my addresses back into contact, I tried to “fix” some warnings in the Akonadi message window, now I have achieved a total failure and do not know any way back,

Mysql worked before, how can I “reset” things?

Akonadi - KDE UserBase is not giving me any further clue.

I liked kmail, don’t want to give it up … what must I do?
