[Plugin: WP-AutoSocial] Unable to get Auo-Social to work

I guess I would need some help as I’m trying to configure the auto-social plugin on my wordpress blog.

After entering all the setup information on the twitter and facebook.

I got a https://twitter.com/#!/404 link when i perform the twitter link test.. and when i click on the get token for the facebook setup, the error message
{
“error”: {
“message”: “Invalid redirect_uri: Given URL is not allowed by the Application configuration.”,
“type”: “OAuthException”,
“code”: 191
}
}
showed up.

I guess i must be doing something really wrong.
