I got a problem with the current version of WPBook 2.5.3 or with Facebook.
After a couple of hours I get the error message "Your Facebook Access Token for WPBook has expired...". After using the "Checking permissions" function in WPBook the message disappears because a new token is set but after some hours it starts over.
I think it is something because of the deprecated offline token access but I can't find the error in my fb settings.

I have tried it with activating and disabling the "Remove offline_access permission". Always with removing the app from the user apps, renewing the secret key and given the permissions through the wpbook "Checking permissions" function. But I still don't get it to work properly.
I really hope you can help me with this.
