Since updating to 4.3.1 we are having an issue with permalinks. Our usual practice has been to have a unique article number serve as the postname, and that would be used in the permalink – for instance:
http://our-site.com/1408558
As of the update to 4.3.1, WP automatically appends “-2” to the slug, mimicking behaviour as if a similar post already existed, which it doesn’t.
http://our-site.com/1408558-2
While that obviously works fine, it disrupts our normal means of structure and organization for the site.
Here’s what I’ve done so far to investigate:
I’d rather not have to add a non-numberic character, and we can’t roll back to 4.3 – so I’m really hoping someone else can help me figure out what changed in numeric permalinks going to the most recent version.
I had the same issue. Couldn’t name a page just numbers.
Wordpress Version 3.3.1
I solved this issue by using a plugin called “Permalink-editor” version 0.2.12

After that was installed, I am able to clicked “Customize” instead of “edit” permalink on the page edit. That worked! 🙂
