I didn't have File:Undefined, but my comp did something weird with images a few years ago. Turns out some stupid extension had installed itself on Chrome that was redirecting all of the image links on the site. So, check your Chrome extensions and disable any that you didn't install or that look iffy. Hopefully it helps~ :)

(If not I have no idea lol :P)
