Side bar and footer gone or can’t be seen on monitor

I recently downloaded the New Yorker theme and was changing the names of the Links page and adding some code for affiliates. Everything was working fine yesterday, until i refreshed my page and the right side bar disappeared or got pushed down and the footer is completely gone. you can go to https://www.thefashionslinger.com. I reset the code for the right side bar and still nothing. I’d like to have the right side bar back, but don’t know what to look for. is this problem inherent to the theme itself? Thanks.
