In your Facebook application, on the "Web Site" tab, update the following:
Site URL:
reviewbahrain.com/
Site Domain: reviewbahrain.com
The error is saying that we (JFBConnect) are trying to redirect the user after they log into a page that isn't owned by your application. This is a basic security check. Since your Application is set to www, but your page is really non-www, you're getting the error. That's also why we give the warning to update it in the overview page, because Facebook can get very picky about these things.
Hope this helps. Let us know!
