Looks like there is something wrong with the root_url.
Leave it as it is (don't put the domain), limesurvey will find it's way.
So I have seen that you have installed Limesurvey under
www.timestar.org/limesurvey
I can see there, that the images and CSS is missing. That shows me, that the path is not correct.
This is what you should put into your $roolurl, if your limesurvey files are located under
www.timestar.org/limesurvey:
$rooturl = "http://{$_SERVER['HTTP_HOST']}/limesurvey";
Try it with the exact term above, leaving {$_SERVER} as it is. This should work.
