I noticed that for some reason on my site, the post order changes depending on whether a user is logged in or not. When I am logged in as the admin, the posts display is chronological order. But when I log out, the oldest post is displayed first, then chronological order, and then the newest post is at the bottom. What is going on here?
Update: I checked my theme's functions.php file and the extras.php file (which includes extra functions) and neither of them have any filters affecting the post order.
Update: I changed my theme to Twenty Sixteen and am still having this issue. I also am on a clean install of Wordpress. Then I updated Wordpress to make sure I didn't accidently change something but I still have the issue.
