Thunderbird calendar disappear after updating

Asked By 10 points N/A Posted on -


I am using Thunderbird calendar for a few days now to manage my schedule easily.

I updated it yesterday to version 11.0.1 but after updating when I restarted it, the calendar was not displayed.

I restarted it several times, but the same problem was seen. I got the following error on the screen:

When I scroll down the error statement, the following message is seen: [Exception… "Component returned failure code: 0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE) [nsIJSCID.createInstance]" nsresult: "0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE)" location: "JS frame:: resource://calendar/modules/calUtils.jsm-> file:///C:/Users/Terradepta/AppData/Roaming/Thunderbird/Profiles/396inyyy.default/extensions/%7Be2fda1a4-762b-4020-b5ad-a41df1933103%7D/calendar-js/calUtils.js :: createEvent :: line 55" data: no]

How can I get rid of this error and view my calendar as early as possible? I waited long for this update, and when the update was released I went through it thoroughly about what will be its consequences on my system. Still I experienced a problem.

Please before updating your software be very sure how this update is going to effect the present add-ons on the system. You should always have an opportunity to back out of the update if you see anything suspicious regarding your add-ons.

How can I back out of this update to remove this error because I tried it myself, but the system won’t let me do it. I suggest to all of you guys to study the update fully before accepting it for your system otherwise the whole family of application add-ons is affected. I have posted this problem to many forums but still didn’t find a solution.

Can anyone please guide me in resolving the issue?

I am badly stuck at this. Your sincere suggestions are required in this regard Thanks and have a good day Peter

Thunderbird calendar disappear after updating


Hello Bessierromero,

As you have stated above, this error started occurring after you updated thunderbird to the latest version. That explains why you are getting the error. It seems the updated version is not suitable for the operating system you are using right now and therefore you will need to do the following:

  • Revert to the old version of the Thunderbird calendar that you were using. That version is suitable for the operating system you are using right now..


  • You can as well check the system specifications of the updated version of thunderbird and then make sure that you install it on an operating system that is suitable to it.
