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:
- Deactivated all plugins - same behavior exists.
- Changed to 2015 default theme - same behavior exists
- Went back to a site running 4.3.0 - didn't encounter this problem
- Refreshed permalink structure - same behavior exists.
- Added a non-numeric character in the permalink - problem goes away
- Changed permalink structure to /testing/%postname%/ - problem goes away
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.
