[Theme: Charitas] Code editing problem-Please help!

Hi! I messed with the code of a free theme I was using. I both re put in the code I had copied before I started messing with it (didn’t work), and deleted and uninstalled the theme, but the mess up is still happening. I was trying to delete some of the footer text and now the main image starts to load then won’t show up.

The theme is Charitas Lite.

Thank you so much!
