Too many redirects can be for a few reasons. First, try disabling any Social Profile plugins you have enabled and test again. If that helps, re-enable them one by one and only enable the ones you need (don't enable plugins for extensions you don't have).
Next, check your New User and Returning User redirection settings and make sure they are set properly and not to a menu item that's set as Special or some other menu item that may not work for registered users.
Finally, you look to have some SEF extension installed; the SEF URL in that picture isn't being created by Joomla's normal SEF. Try disabling that SEF extension, temporarily. If that works, there is usually a way to 'skip' SEF URLs for specific extensions. You'll need to tell your SEF extension to 'skip' JFBConnect and JLinked.
Hope that helps,
Alex
