Yes it does indeed.
The site is only hosted on http, not sure if that could cause any issues.
Happy to provide further details if needed.
Not sure if it’s related, but I seem to be having this issue on the latest version (downloaded and installed today).
I’ve registered the application with Instagram, entered the details and attempted to ‘Login to Instagram’. When I click the ‘Authorize’ button, it’s redirecting me to http://www.example.co.uk/wp-admin/admin-ajax.php?action=register_instagram as expected, but the page is blank and it fails to authorize correctly.
Tried in Safari and Chrome on Mac OSX.
