gregorysforster on "[Theme: Hemingway] 500 Internal Server Error"

Hello everyone,

The other day I put up some new header images and I deleted some old ones. After I saved it and went to check it out on the site the old header images were still there and the new ones weren't. Now when I click on 'headers' or try to customize anything about the appearance of the theme I get the 500 Internal Server Error.

Not sure what to do about it. It happened immediately after I tried to upload new header images so I'm certain it's tied to that. The rest of the site functions as it should. Any ideas? My site is below:

Thanks

Maybe this isn't theme specific now that I look more into it. I changed themes and I am getting the same problem anytime I try to customize a theme.
