I also had the same question, so thank you for the info! This was one of those issues that’s incredibly hard to find via Google searches given that it’s hard to come up with unique search terms that point specifically to this issue!

I added this to my wp-config.php file, as described above:

define(‘SCRIPT_DEBUG’, true);

and that solved the problem of no editing toolbars and not being able to edit widgets and so on.

I had already tried disabling all plugins, switching to the default theme, and all the usual stuff, and none of that worked. But after adding the line above, I restored all plugins and my custom theme and all worked again.

When I checked the Error Console in Firefox, I saw that most of the errors were coming from bad code in the Gravatar CSS files as well as other files I have no access to.
