For 8 days now I have been struggling with this problem and now I'm starting to suspect something about my internet connection, though I only notice the problem when working on my website.
I have a self-hosted Wordpress website. Starting 8 days ago, whenever I made a change in the back end, such as change my layout or add a widget, the change does not show up when I reload my website for a long time (like a half hour).
This happens in all three browsers, Safari, Firefox, and Chrome.
This happens with any theme I choose to use.
Yes, I have cleared my cache and history. And it happens in Private browsing too.
WHY? Can you tell me why, and how to get this fixed? It's really hard to create a website when I can't see the changes right away.
