Notice: Trying to get property of non-object in views_ui_edit_display_form()

I received the following error after enabling the jquery expander in the display swettings of my view.

Notice: Trying to get property of non-object in views_ui_edit_display_form() (line 3151 of /home/[redacted]/[redacted]/sites/all/modules/views/includes/admin.inc).

When I tried to remove the display setting in views, I get a white screen with the following info:
