Caching Issues After Editing

Hi, I've noticed this problem that occurs with upfront that makes edits I work on with the site completely bonkers when I check from another computer that has already visited the site. I'm trying to find a way to fix this issue. Mobile for example is just so bad. Please help. Seems like a caching issue but I can make everyone who has ever visited the site clear their browser data so I need to be able to do this. Hope this is making sense.
