Please re-install JFBConnect. The image you're showing above is indicating some required files for JFBConnect have not been installed. There should be files named facebook.php, twitter.php, linkedin.php and google.php in the /components/com_jfbconnect/libraries/provider folder. From your image, it seems like those are missing or that there's an issue reading your filesystem to find those files.
Hopefully a re-install is all it takes, but if not, please let us know.
Thanks,
Alex
