Facebook returned the following error: redirect_uri isn't an absolute URI. Check RFC 3986.


Users currently can't connect to with the above error.

Please respond to this as soon as possible as I've just started a drive to bring users to our forums, only to have them kicked out with an error.

Not using facebook connect is not an option.

Thank you,

    my guess is something is interfering with Url function. Do you know of anything that may be overriding the Url function?

    It needs need the full url to be built.

    in /library/core/class.request.php

    it defines the host as

          $this->RequestHost(     isset($_SERVER['HTTP_X_FORWARDED_HOST']) ? ArrayValue('HTTP_X_FORWARDED_HOST',$_SERVER) : (isset($_SERVER['HTTP_HOST']) ? ArrayValue('HTTP_HOST',$_SERVER) : ArrayValue('SERVER_NAME',$_SERVER)));

    so if those server variable are being striped it won't provide a full url.

    Other wise, facebook is known to be extremely strict, an it may be confused by an url.

    grep is your friend.
