On my site, I have permalinks for different categories. If I have a forum with the same name as one of the categories, then the permalink for that forum will have a “-2” added at the end. For example, if I have a travel category and a travel forum, then my travel category will have permalink:

http://www.example.com/travel

While my travel forum will have permalink:

http://www.example.com/forum/cat/travel-2

Here, I changed the Forum slug in the backend to “cat” instead of “forum”.

Why would the forum permalink add a “-2” at the end? Every time I try to update the slug to the forum from the backend, just adding “travel”, when I save it, it comes back to me as “travel-2”. This one has me stumped.

WordPress does not have hierarchical collision detection for full paths. This means no two posts can have the same slug.

There’s no workaround to make it do hierarchical collision detection?

Unfortunately, not currently. That would be something that would need to done on a WordPress core level. I’m not aware of that being an issue they are going to address soon, but maybe I just haven’t seen it in WP trac.

I see. Thanks for clearing that up.
