Hi Sandra-
I checked out the website you sent over, and I do see the default “Hello World” WordPress page. I can think of a couple of things to check to make sure your site gets published.
First, I can see that your site is running WP Super Cache, so it’s possible that you might need to clear your cache before you see the changes to your site. Look for the Delete Cache link at the top of your WordPress dashboard.
Second, it’s possible that you might be working on a staging site. Double-check that the URL of your published site matches the URL of your live site.
Third, it’s possible that your site might be saved as a draft. Navigate to your Customize menu, and make sure that the blue button says Publish and not Save draft or Schedule.
