Posts and pages

Hello, I am having trouble with the site’s pages and posts loading. My site is still on my localhost. My page that I use as my “homepage” will load, however no other pages or posts will generate on my front end of the site, even pages that have previously loaded. I am using the “Make” theme by The Theme Factory. I have been customizing my theme appearance from the front end editor extensively, however I have not manually touched the theme’s code as I do not know how to code myself.

I noticed this issue as I was trying to make post categories pages, for my separately categorized posts.

If anybody could give me insight on why these pages won’t load, it would be appreciated
