How to Fix Divi Editor Can’t Open Modules (TypeError: n(…) is not a function)

After migrating a Divi site to production using the All-in-One Migration plugin, I discovered that I was unable to edit any sections, rows, or modules in the Divi editor on the migrated site. In the console, I got the error:

bundle.js?ver=4.27.4:2 [React-imported-component] TypeError: n(...) is not a function

The front end of the site was fine.

I tried all of the usual tricks, including clearing caches, disabling plugins, Divi Safe Mode, resaving pages, and so on. Nothing worked.

The Solution

Finally, I decided to upload a fresh copy of the Divi theme, and that worked! I was able to edit modules again!

To do this, download the latest copy of the Divi theme from their website, then in your site go to Appearance -> Themes -> Add Theme, and have it replace the current copy.

Go back and try to edit a page now. It should work!

What Caused the Problem

I’ve never seen this problem before when using All-in-One Migration to push to a non-Divi site.

So, my theory is that when I used All-in-One Migration to upload the new site, it didn’t overwrite some files from the old Divi site, which messed things up. Hence only a fresh upload of Divi solved it. But, that’s just a guess.
