--- Comment #2 from Alexandre Bonneau <alexandre.bonn...@linuxfr.eu> --- For information after trying all the hacks and tricks I learnt using akonadi, I couldn't find how to fix or work around that critical bug. I had to remove the calendar resource, and recreate it from Nextcloud. So far it works again. All that points out the bug to, as always, akonadi and how it (badly) stores data and/or manages errors it introduces. This bug is still critical, a word from devs would be great! -- You are receiving this mail because: You are watching all bug changes.
