Local calendars fail to display
I have 3 local calendars that I regularly synchronise with local calendar on my phone using MyPHoneExplorer
With the last thunderbird update, all events in some calendars disappear and sometimes reappear spontaneously or using a backup of the local.sqlite file in the calendar-data folder.
For the moment, in one calendar, no event are displayed though they are present (using http://inloop.github.io/sqlite-viewer/) in local.sqlite. When I create a new event in this calendar, it is diplayed but it does not reappear if close and open Thunderbird or if I turned off and on the display of that particular calendar.
A week ago, it was another calendar that shows that erratic behaviour.
Any idea how to solve the problem ?
