No calendars listed, events appear dimmed

[gdso...@gmail.com]

Since couple of weeks I'm Having problems with Lightning. I'm using Thunderbird 68.3.0 with Lightning 68.2.1 and all my calendars are from Google. Most of the time after I start Thunderbird the calendars are not listed, the events appear dimmed and the daily agenda on the right is empty. I cannot make any modifications to calendar events, no notifications are generated, so calendar is pretty dysfunctional. Initially I though it's a problem with Provider, but I think it's more related to Lightning. In the console I have many such errors:

[Exception... "[JavaScript Error: "currentView(...).startDay is null" {file: "chrome://calendar/content/calFilter.js" line: 513}]'[JavaScript Error: "currentView(...).startDay is null" {file: "chrome://calendar/content/calFilter.js" line: 513}]' when calling method: [calIObserver::onEndBatch]" nsresult: "0x80570021 (NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS)" location: "JS frame :: resource://calendar/modules/utils/calDataUtils.jsm :: notify :: line 40" data: yes]

Anyone having similar problems?

In my 68.3.0 my Lightning is version 68.3.0 and the Provider extension
is version 68.2.1.

I'm not having any problem.

You should be able to update to Lightning 68.3.0 using "Check for
Updates" from the gear wheel icon in the Add-ons Manager. There doesn't
appear to be a version 68.3.0 for the Provider extension.

Do you have other calendar extensions installed that could be causing a
problem? Try disabling them and restart Thunderbird.

Yes, me and I fear many others.
I've been through the same reasoning as you, and have also come to the concludion that it's a Lightning problem, possibly associated with the presence of other add-ons.
I'm seeing a lot of errors in the console too, in particular, identical with yours:

[Exception... "[JavaScript Error: "currentView(...).startDay is null" {file: "chrome://calendar/content/calFilter.js" line: 513}]'[JavaScript Error: "currentView(...).startDay is null" {file: "chrome://calendar/content/calFilter.js" line: 513}]' when calling method: [calIObserver::onEndBatch]" nsresult: "0x80570021 (NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS)" location: "JS frame :: resource://calendar/modules/utils/calDataUtils.jsm :: notify :: line 40" data: yes]

@WaltS48 - I'm using same versions as you, TB 68.3.0, Lightning 68.3.0 and Provider for Google calendar 68.2.1.

I'm able to get both to work, by removing them and then adding them again. But Lightning will not survive a re-launch of TB. Until recently it did, but now it gets broken every time I exit TB. So I don't exit TB unless I really need to (hibernating in Windows).

Suggestion: Go to the Calendar tab. Have you chosen 'events in current view' as your events list filter? If so, try selecting anything else, such as 'events in this calendar month'. Then close and re-open TB. That seems to restore display and function of the calendar, events, etc (permanently). Well, it's a workaround at least. I would very much like to use the 'events in current view' filter, so hopefully it can be fixed.

This suggestion resolve the problem with calendar list.

Thanks so much for that workaround! Works for me.
