All themes are defaulting posts in ascending order and I want to change it

Newest posts first should be the default order. It is possible for a theme to change this so that oldest posts appear first, but if it occurs in all themes you have tried, including default WordPress themes, a plugin may be affecting it. To check for this, temporarily deactivate all plugins. If this fixes it you can activate them one by one until the one that caused this is found.

I couldn’t see the issue on your blog as the posts seem to all be posted on the same date.

Thank you! I’ll try that now!

I deactivated all plugins and the post are still in ascending order. All of the posts were published yesterday but the newest should be at the top based on the order they were published. Please help. Should I actually delete all of my plug-ins?

Can you replicate the problem using the default Twenty Thirteen theme with all plugins deactivated?

Yes, I just installed and activated the Twenty Thirteen theme and it’s still doing the same thing. I took down all of my post and reposted them and the order is the same. The newest post is on page 3.

I think I figured out what was wrong. When I was publishing my posts I was altering the dates and times and that messed up the order. Now I’m wondering why only one post is showing up per page? Before I launched my post were showing up in a continuous scroll.
