Updating site, saving, publishing...changes not showing up.

My site is https://bfccityconcens81518.homesteadcloud.com/ and I have tried this on Firefox and Edge.  I make updates to a couple of my pages, I then save, then publish, but now an hour later the changes are still not showing up.  I had the same problem yesterday, too.  Is there someone who could check into this, please?  I'm building this for a non-profit and would like to make a good impression but they're not seeing the changes I'm making. Help!
