I have run into this issue as well.

I am using a clean Drupal install, currently sitting at 7.16.

I am using all of the dev versions of ctools, calendar, date, context, and Views. If I try to make any changes to the Events Calendar view, I get a white screen of death, and I get an error in my logfile, with the following:

[Mon Nov 19 04:17:11 2012] [error] [client blah] PHP Fatal error: Call to a member function summary_title() on a non-object in /var/data/drupal/sites/all/modules/views/plugins/views_plugin_display.inc on line 1192, referer: http://blah/calendar/month

I have worn out my fingers searching for a solution, and my forehead is about to go flat!

Appreciate any help that can be offered.

I have solved this issue by using old release 7.x-3.4. Most of the drupal recommand module in drupal 7 crash the drupal. I feel drupal Association and Drupal guys should attention to this issue. If a module is recoomand then it must be free from bugs and fatal errors. Many of the modules went in my eyes which are recommended but full of fatal errors and bugs.

I tried the 3.4 version prior to going to the dev version, and got the same error. Then upon reading, I saw the advice "make sure you are using dev versions of everything", which seems counter-intuitive to me. I'm not sure going back to 3.4 will solve the issue I'm having, but I will give it a try with 3.4, and dev versions of everything else.

Hi rwhittaker

First uninstall the calender module (3.4) and remove the calendar module directory then use this as i have attached.

If you face again any issue then come back again

I was able to resolve the issue by rolling the calendar module back to 3.3, and leaving all the other modules at their dev versions. Now there are no errors. Makes me really scratch my head and go.. "Huh?"...

I'm having the same issue. If I uninstall the module, will I lose all the data?

Version: 7.x-3.4 » 7.x-3.x-dev

I have run into this issue as well. I have not yet found a solution or cause yet. It affects all versions it seems to me, including the dev version. I'm not into doing rollbacks, that is counter productive.

I experienced this issue with the same error on an under-development site that I haven't touched in months. After updating to the latest stable version of views, date, calendar, and Drupal 7.18, I found my calendar views were blank and I was unable to edit them.

According to the following thread, recreating calendar views is the only solution.

I had this problem. I just exported the "Events calendar" view, copied the code, and then imported the code back in to create a new view. It works.

The suggestion in #10 worked for me. Thank you, @hyperlinked!

#10 worked for me too. It also solves the white screen when trying to edit the view.
Thanks @hyperlinked
