Starting a couple days ago on my site, I found that when I make changes to a page or a widget, instead of showing up immediately upon refresh, it's been taking a couple hours for the changes to show up. Clearing my cache doesn't help.
I don't know where to start looking -- would this problem be client-side (something with my computer, my browser) or server-side? Could this be an ATA-related problem? A plugin-in? Or is it more likely to be an issue for my host (Hostgator)?
