My site url at facebook development page is correct i've followed his steps hundreds of times

have you setup the ENV for facebook key and secret? in console that you are running the app from? — Pritesh Jain, Sep 06 '12 at 03:02

May be you have not setup the env for FACEBOOK_KEY and FACEBOOK_SECRET

In terminal (if you are using linux or mac)

$ export FACEBOOK_KEY=zzyzyzyzyzyzzy
$ export FACEBOOK_SECRET=zzyzyzyzyzyzzysbdbdsndnds

#now start rails from same terminal
$ rails s

this will now pass the values of FACEBOOK_KEY and FACEBOOK_SECRET to application.

Or second option

provider :facebook, ENV['FACEBOOK_KEY'], ENV['FACEBOOK_SECRET']

to this

provider :facebook, 'FACEBOOK_KEY', 'FACEBOOK_SECRET'

Diff between using two approaches.

The drawback of second type is, you need to keep the keys into the code repository. which is not a safe approach.
