When I look at the site I see that your sidebar is actually overlapping 233px of your content. See this screenshot. It looks you modified the theme and added 233px of left margin, that is what is causing the problem.
It looks like the original theme had at 950px container that was made into a 1200px container and this through off the entire grid. What you need to do is get rid of the padding left on your sidebar and then open up your screen.css and change the .span-16 element on line 113 to a width of 880px. That should do the trick. Let me know if that doesn’t work.
i got it! thanks for all your help. yea instead of changing the span-16 to a higher width, i just changed the php code of span-16 to span-22. once again, thank you so much. i am very pleased with the help i receive on this site 😀 just amazing.
