Calendar disappeared with Thunderbird 60.2.1

[hakelm]

My Lightning Calendar disappeared with Thunderbird 60.2.1 update.
The calendar is said to be incompatible with 60.2.1.
Is there any way to recover my calendar data?
Is there any way to restore the previous version of Thunderbird?
Thanks in advance for any tip.

How did you install Lightning?

Do you use your Linux distributions build of Thunderbird?

Try removing Lightning then open a Terminal and type

Code: Select all

sudo apt-get install xul-ext-lightning

If you aren't using Linux see https://support.mozilla.org/en-US/kb/ca ... hunderbird

Thanks a lot,
worked like a charm in spite of the add-on page stating:
"This add-on is not compatible with your version of Thunderbird.".
Another minor problem is that the update convinced Thunderbird to talk English instead of Swedish.
