Facebook Service problem

Hi everyone!

Its my third topic in few minutes, so I hope you guys dont hate me! :)

My last problem is about Facebook_module service. I create a tool/application on Facebook Developers, getting a ID and Password.

I try to use those parameters on my facebook_service module, but I cant connect it with my Elgg.I inster the info on the fields, and then, in Settings, when I click the link to connect both, Facebook developers show me a bug message.

I use Elgg 1.7.

Does anyone know anything about the problems with that module? about solutions?

 

Thank you so much, community :)
