Open your File Manager, located on the URL drop down menu in the upper right corner of your page editor. Find the page on your content list > select the line > click the yellow Publish Flag. Let me know if this works for you.
The pages seem to load for me. Are you still having a problem? Some were a little slow to load as they have quite a few images on there. If it is still having an issue, click on page settings and go to background, links & footer, then toggle the background to something different and then switch it back again.
