Ouch. You've got five external stylesheets, wads of separate CSS declarations-- including at least one in the <body>-- AND inline styles. Get that all cleaned up and organized, and you may well find that the problems fix themselves.

Well. That's an hour of my life I'll never see again.
At first glance, the problem seemed to be in the social-media icons. Comment them out and the problem goes away. Leave them in, and the social-media bar behaves as if it were set for position: relative with a substantial left-offset.

The problem only manifests itself if the ul has visible content-- here, the icons.
Yes, OK, so I was mistaken. Not a left offset but a negative right offset.
In short: The page is doing exactly what you've told it to do ;)
Incidentally, the main image is way too big. Filesize, not physical dimensions. You can easily get it down to 100k by changing to a lightly compressed jpg. The png format doesn't generally work well with subtle color gradations.
