Calendar blank/empty after upgrade

Just did an apt-get upgrade of my system; now there is Thunderbird 60.4.0 and Lightning 6.2.4. After restarting Thunderbird, I see the calendar tab as usual, see my subscribed list of calendars, but no entries of neither calendar are shown, ie, no events shown, calendar seems empty/blank.

Also nothing is shown if a new calendar (network, local ics file which contains entries) is created.

I am also using the extension "Provider for Google Calendar" to sync with my Google calendar. Just before the update, everything worked fine.

It seems the update corrupted calendar-data/cache.sqlite. Deleting this file solved the problem.

(Found after activating debugging (setting calendar.debug.log and calendar.debug.log.verbose to true and looking at the error console revealed NS_ERROR_FILE_CORRUPTED)

If dakrenn's "explanation" of deleting the files went right over your head, go to options,, advanced, Config Edit, ignore the scary notice about your warranty, find the two files he mentioned, right click on them, and toggle them to True. My calendar is still blank, but who knows, you might have better luck. So much for all the doctors' appointments and radiation treatments I have set up for the next several weeks.

Those Config. editor calendar prefs. just enable logging. Did you delete the cache.sqlite file (while TB was closed)? There are some other troubleshooting tips here. The first section on resetting Lightning may work in your case.

Re: reply from sfhowes I've done all the steps in "Lightning disappears after a Thunderbird update (release and beta versions)" several times. The calendar stayed blank after each try. I even uninstalled Thunderbird and reinstalled it thinking that might help. It didn't.

Is it a network or local calendar? If the former, e.g. google, maybe you need to update the provider add-on.

Just local.
