First of all, its time to update tutorial for this plugin, and the links for that. The tutorial for creating an facebook app is outdated for ages!

I've created the app, but the second step of the config for the plugin always fails.

If i click on reset auth tokens i got this:

App is alive.
The screens are very different from that ones from the tutorial.

When i try to add the app domain at facebook, i always get this:
