Admin page is white after fresh install with "Deploy to netlify" and Gatsby


I just started a fresh install with the “Deploy netlify” button with Gatsby and the admin page is white.
I have these two errors in the console :

  • Uncaught TypeError: window.REDUX_DEVTOOLS_EXTENSION is not a function
  • Uncaught ReferenceError: NetlifyCmsApp is not defined

The admin page:

Have you got some ideas about this issue?

Thank you,

hey there,

this is what i am seeing:

the errors you mentioned indicate that you have some browser extensions that are causing issues.

I would check the URL in an incognito window and see if that fixes things.

Thanks for your reply !

It works on incognito window…
The issue is due to the XState DevTools extension… Don’t know why…
It works now, thanks again.

great. Browser extensions are so awesome in many ways, but they can cause unexpected behaviour, that’s for sure!
