For a few months, when I load some of my Google Drive wordprocessing docs, I get the Jacascript popup error in Chrome (latest version):
This error has been reported to Google and we'll look into it as soon as possible. Please reload this page to continue.
Pressing "OK" re-loads the page, and gives the same error.
I can "Make a copy" of the doc which solves the issue, but obviously loses all revision history. I've tried disabling all 3 extensions (2 REST clients and "XML Tree").
