Login using Facebook/Twitter not working

I’ve tried to login on this forum using facebook and twitter and I got these errors:

FB: [COLOR=rgb(51,51,51)]App Not Setup: The developers of this app have not set up this app properly for Facebook Login.

Twitter: [COLOR=rgb(89,89,89)]There is an error with your Twitter application settings.

It would be nice to have these options enabled…logging in would be easier.
