Index (Home) page not showing up properly!!!

My website was ALLLL good until recently! I have not installed anything new either.

Whenever I go to my website, https://www.josimarie.com, the main page doesnt look like it was organized before. The sidebar content on both sides are missing. I shrunk the page and saw that the sidebar content was totally somewhere else.

When I go to any other page or blog, my website shows up correctly!

Please help!
