Problems with newest post showing up on blog section

Hi there!

I’m having issues with my most recent blog post showing up on my blog section.

This is the one that’s currently showing up as the most recent, but this is the one that should be showing up. The only way I’m able to find the true newest post is when I click on the Archive month.

Additionally, when I click into the post that’s showing up as most recent (but really isn’t), I don’t get the button on the side of the screen to advance to a newer post, just the one to go to an older one.

I’ve tried a number of things: uninstalling plugins, using different cache plugins, resetting browsers, completely deleting the post and starting over, doing things with my hosting plan—nothing’s working. I’ve tested going to my site on devices that have never accessed my site previously, and everything’s coming up the same.

Do you guys have any ideas on what I can try? Thanks!

Best,
Alex
