Homepage not displaying correctly

Hello!

Something funky is going on with Winooski’s site, and I can’t seem to troubleshoot it. This first started when I realized that the header and background pictures were associated with my old staging website that I was using to set up their new site. I went in and fixed the background and header and now the homepage is not loading correctly. It seems to be fine on other pages though.

Here’s the website: https://www.winooskivt.org/
