Since today, I'm no longer able to edit a specific Google Spreadsheet. Every time I try to make an edit, no matter which kind, an error message is displayed:
The action you're trying to perform is causing a fatal error and cannot be performed.
This happens wether I edit manually, or attempt to modify cells via script. The script will fail with the above message, either when the script ends, or on a SpreadsheetApp.flush() line.
Only one spreadsheet is affected. I have shared it with another account, but the error occurs on both accounts. There is even a Google Apps Scripts webapp that adds new rows to the sheet, which now also fails.
I did have an On modification event handler, which I have now disabled, but the problem persists. And I have not made any changes to any scripts.
Edit: A day later, the error message has changed to
Oops: A server error occurred. The page will reload
I normally use Google Chrome v. 32 on Windows 7/XP, but the problem exists also in Firefox 26 and Internet Explorer 9. I have disabled all browser extensions.
I tried making a copy of the problematic spreadsheet, and the copy works fine. I could have just used the copy, but that is hardly ideal when the URL to the original has been shared with collaborators.
What are my options for debugging this issue?
