Dont know why, but preview is previewing an old stage of creating a website and I cannot make it show me the current work.
Clearing cach does not help.
Making a new template and previewing it, works.
This last update broke it even more...
Did you try closing the browser and reopening the preview again? I've had the window get stuck on a page for me at times and I've had to close the browser preview and reopen it. Also, be sure it's not a cache thing, that is a horrible issue for me with Chrome these days.
