Hi Guido,
I don’t know the exact location for the addons.config from the top of my head.
But when logged in in the linux, search with the command: sudo find -name “addons.config”
This should give a result where it’s located.
Open the file with a text editor like nano.
In this file I had to remove the actions for mail, in my case.
I hope this helps.
Best regards,
Edwin
