Did you get it to work, Monon4ever? The same thing is happening to me today and I was wondering if you had a fix for it. When I changed themes, my customize worked, but as soon as I changed back, it was just the spinning gray ball again. It’s getting frustrating. My entire admin wasn’t working, and I was on customer support chat with my web host for over an hour. Got everything working except for this….they then said to ask wordpress customer support. I haven’t yet, as I’m hoping to find the fix in these forums. I am using the the evolve theme. What theme are you using?
