Problem with HTML Code on my site.. Help me!

Hello all. Yesterday, i updated wordpress to the latest version and my website's html code seems to have changed or something is missing.. I'm getting a white box on Channel 1 and Channel 2 ( Magic-Sportzz - ) while the homepage is all white!! ( Magic-Sportzz | ). Can somebody help me with the html code and give me a solution as i can't find where the problem is..

Thanks

I see white text on your pages. Check your theme.

I know there's white text as it would fit with the background image (grey). Anyway i tried changing to red only the text changed, the white "box" wasn't removed..

Can someone please help me? Why there's a white square on my site? It appeared after the latest Wordpress update! What's going on?
