Created attachment 8870910 [details] BlankEditDialog.jpg User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 Steps to reproduce: 1. Click on 'Calendar' tab 2. Select an existing event created by me 3. Click 'Edit' button from toolbar below 'Calendar' tab 4. Observe that 'Edit Event' dialog comes up blank Actual results: 'Edit Event' dialog is blank. Same result occurs if I reach the 'Edit Event' dialog through right mouse click, 'Open' over an event, or double-clicking an event. This only occurs on events that are editable by me. Events created by others are read-only and I'm able to see content in the dialog. Expected results: I should be able to edit the event. Change the title, time, etc.
Does this behaviour also occur with all addons but Lightning disabled? Some extensions like the Beehive or EWS provider extension are known to cause this issue.
This is an error caused by Oracle Beehive Extensions for Thunderbird.
