When coming back from Mautic authorizing the ninja-forms install, the page does not notify that it's been authorized sucessfully

[isleshocky77]

When you successfully authorize a Ninja-Forms website from Mautic you return back to the settings page and it still shows you the box for keys and the Authorize button.

If you click on Form > Settings again, you'll notice that it now does not display the API text boxes and shows "Re-Authorize" instead.

wp_redirect when coming back throws an exception that headers have already been sent so that cannot be used.

Is this on oauth1? I was having a similar issue but switching to oauth 2 fixed it.
