in debug view the error shown is “24 May 2017 05:11:40 PHP 5.4.45 Error fetching OAuth2 access token, message: ‘invalid_grant’ :: 400 “
I also have the same issue. The access code doesn’t save. On further debugging it shows the admin-ajax.php 500 Internal Server Error. But admin-ajax is working for rest of the plugins and site. Please advise.
