Do you have Lightning installed, and is it enabled? Which version of Lightning?

Lightning is allegedly integrated into TBird 38. It WAS installed. Who knows now?

I just installed 4.0.2 . The previous version had disappeared and all that was available was Lightning tabs. Thank you.

Had the same problem. I was under the impression that Lightning was now integrated into TB 38. Poking around a bit, I found that Lightning still exists as an addon. Downloaded 4.0.2 and installed it. Calendar back. Easy. Sorry to hijack your thread. Maybe somebody else will benefit!

It's OK Dan. Lightning survived 38.1 and apparently is part of the package for TBird install. But it disappeared with 38.2 upgrade.

I was having this problem as well. I uninstalled and reinstalled Lightning without success. My primary calendar is on gmail, so I use LIghtning so that I can respond to invitations that come to my (non-Gmail) e-mail in Thunderbird.

I finally found that, somewhere along the line, the Provider for Google Calendar extension (1.0.4) had been disabled. I thought I had checked that before doing the re-install, but possibly not.

I certainly didn't disable it. I assume it happened during the upgrade to 38.2 (or thereabouts), because I had been happily using Lightning for a long time when it suddenly stopped working.

When I did re-enable the Provider extension, everything worked again.

I'm posting here in case someone else runs into the problem I had. I can't guarantee that a Lightning re-install won't still be necessary, but some combination of that and making sure the Provider extension is enabled did work for me.
