Webpage Not Displaying

For some reason, all of a sudden, our homepage is not displaying correctly. Instead of populating our normal homepage, our blog shows up instead. And when you click “Blog” from the menu the page that typically is our blog doesn’t show up or populate at all. This just started happening today. I have tried to change the settings on the back end, and it seems like the problems are fixed when I click preview, but then when I switch growers or try to test from separate device the problem still remains. Running 4.5.3. Any help would be greatly appreciated.
