Permalink keeps using month and post name

Well I kind of understand why now. The real file sits in Uploads/yyyy/mm folder with hashed names.

I’m using this WP DR add-on to remove document dates from the permalinks: https://github.com/benbalter/WP-Document-Revisions-Code-Cookbook/blob/master/remove-date-from-permalink.php

If you’ve already created documents, you’ll need to use a plugin such as Better Search and Replace to update the database.
