You may see a 404 or you may not :/

The latest blog post will randomly 404. There are no traces of the 404 in the error logs. Saving permalinks will fix the issue but the problem will reoccur. NOTE – THIS ONLY HAPPENS WITH THE LATEST POST.

I have tried resaving permalinks, deactivating plugins 1 by 1, and a default theme. I’ve read random 404 fixes until I’m blue in the face. I’ve scoured logs.

Any suggestions on how to track this down would be greatly appreciated.
