Posts Published But Not Showing Up

I run 3 different WP sites and have never had this happen. On the site I have only had up for about a month or so I just noticed that the posts I have made haven’t actually been showing up on the page/category I published them under. They are listed as ‘published’, I can see them on the side bar and in my dashboard but there’s nothing under the category at all on the actual site. Just a blank page. I have poked around my other sites the last 3 days to see if there’s something I am missing but nothing seems to stand out. Any thoughts/ideas?
