I’m trying to use the Facebook’s Registration plugin and i keep getting this error:
“That ‘redirect_uri’ isn’t allowed for that client_id.”
My settings in FB:

Source:
<div id="fb-reg">
<fb:registration
fields="name,birthday,gender,location,email"
redirect-uri="http://www.facebook.com/develtestpage/signupsuccess.php"
width="530">
</fb:registration>
</div>
I found a few article but it should work…
Change your
redirect urifromhttp://www.facebook.com/develtestpage/signupsuccess.phptohttp://cold-dawn-9801.herokuapp.com/
