The easiest way to do it is via terminal. If you can open one (program's name on KDE: Konsole) then typing
- Code: Select all
rm -r ~/.config/akonadi
should do the trick.
The way via file manager would be to open one, go to your home folder, make sure hidden files are visible (there should be a checkbox in the wrench or cog (I forget which) menu), go in the .config directory and delete the one named akonadi.
