The simpler media website CMS
I redid my server recently (Ubuntu 18.04 -> 20.04) and copied over the original files and database as-is. I'm not sure what's wrong, but I can't view any images from the main site.
If I go under the admin panel, I can still see my albums and images, and if I go to a direct image from there, it loads.

You should review your PHP error log. The content of the page is truncated which mostly indicates some fatal error.
