Page content not showing

I am using WordPress but not as a blog, i.e. all my pages are “pages” and not “posts”. I have had the site for several months with no problem.

Today I made two new pages. The first one looks fine. The second one, which I published right after, is not showing any content at all. The theme and links look as normal, and all the links work except for the new one.

The site is at https://www.mybestgurus.com and the faulty page is called Niche Profit Classroom Review (the link works, just nothing on the page.)

I’d really appreciate help with this. I don’t understand how one page works and another made right after doesn’t. Thanks.
