[Facebook Login Plugin][iOs] - Can Login, but cannot Logout

  

Cheers,

When using the Facebook Login Plugin in an iPhone 6, login happens just fine, but when the user tries to logout, the device receives a message with 'null', instead of 'ok'. This plugin works well in Android, but fails to logout on iOs. The user seems to remain logged in?

Has anyone ever had this problem before? How did you solve it?

We've tried to search what error means a 'null' message, but to no avail.
