My site is acting strange ..

Homepage is acting strange there is a blank page on the bottom, plus all the site text on homepage getting bigger and there is a " ONE" on the homepage. I did not change anything on the site for over  week. it just change by itself or someone put that "one" just 20 to 30 minute ago. the problem is only on homepage because of that "one"

Please Help!  Check the image you will see what I am talking about...

The problem was in index.php not in design.inc.php

The code you see in design.inc.php is normal. It's dolphins encoded licensing system.

I fixed it. But i sent you a PM. I need information about one of your mods that goes in that file.
