Theme compatability?

Here is my site http://www.blunttrauma.net/can/
I have the Kingsize Theme
I am having several issues:
For all screens,
When i scroll down a random white bar appears on lower left of screen
When i type in any search bar it is white text on a white background.
Most of the mingle links extend too far to the right and do not align with the theme nicely.
Profile Info text is black on black
Any one else have kingtheme or any advice?
Thanks,
Blunt Trauma
