Lots of issues

I just purchased this and I’m seeing lots of issues. For some reason, the sidebar in google chrome is about 1 / 20th of the size it should be. Everything is smooshed. I tried taking off the sticky sidebar but this didn’t help.

My footer disappeared, I have the menu setup correctly and I have columns setup but now it just disappeared. Also, some of the time I’m scrolling down the page automatically jumps back to the top.
