Duplicate content when appending a digit to URLs

[henrywright]

I've noticed something strange when appending a digit to the end of a URL such as http://buddypress.org/support/

e.g.

http://buddypress.org/support/2/
http://buddypress.org/support/3/
http://buddypress.org/support/4/
http://buddypress.org/support/5/

When I visit each of the URLs above I see the exact same content displayed each time. Should each of these pages result in a 404 page being displayed? Would search engines see this a duplicate content?

Note that when I visit a page such as http://buddypress.org/support/kyathhaggfa I do in fact get an expected 404 page.

This is a bbPress issue and not a BuddyPress one.

To duplicate, add a bbPress shortcode to a WP page (like [bbp-topic-index]). Next, navigate to the WP page and append a number to the URL similar to what henrywright mentioned.

I'm moving this ticket over to the BuddyPress.org milestone, feel free to create a ticket over on ​bbPress Trac as well, henrywright.

Thanks r-a-y for pointing that out. I think this could actually be a WordPress issue too. I am seeing the problem when viewing pages such as

example.com/about-us/
example.com/about-us/2/
example.com/about-us/3/

and on posts (my permalinks are set to post_id):

example.com/5673/
example.com/5673/2/
example.com/5673/3/

Interestingly I don't see the problem when accessing tag pages (my tag base is set to tags):

example.com/tags/soccer/
example.com/tags/soccer/2/
example.com/tags/soccer/3/

Is it worth me raising this issue at WordPress Trac too?

[henrywright]

Raised issue over at WP Trac as it seems to be WordPress related too.

As this issue was fixed in WordPress and deployed in 4.4 and as it's not replicating anymore on BuddyPress.org - I'm closing the ticket as worksforme.
Now bbPress returns nothing and the page itself (its content) is blank on https://buddypress.org/support/2/
