Grant extended permision keeps hanging, menu not working

Hi,

When configuring this plugin, I move from the app-connection data to the next 'Grant extended permision' part.

That part keeps showing the 'loader image'. Als the wordpress-admin submenu dropdown (the default wordpress admin menu subitems) stoped working.

When moving on (skipping that part) other part of pages are incomplete (for example user selection field of auto post facebook part).

Kinds regards,
