I just noticed the same thing my self.
Basically Yoast WordPress SEO: XML Sitemaps automatically adds ALL reply url’s to the existing sitemap. This means google will index them all.
> What I’m looking for are where the single reply URL’s are being used in your theme, making them accessible and allowing them to be crawled.
I doubt they are exposed by default, however a quick fix could be adding a rule in robots txt as well as excluding them from your sitemap.
What I did found is that in 2.3 the class .bbPress got transformed to .bbpress (notice the capital letter).
What that meant was that my full width archive pages got transformed into two column ones, so my immediate thought was that bbPress broke support for archives in my theme.
While I couldn’t replicate the above, perhaps it will help someone and it’s somewhat related to the symptoms.
I think there is a bug in the bbp-twentyten files.
I’m talking about archive-forum.php
It calls bbp_get_template_part( 'bbpress/content', 'archive-forums' );
Notice the ‘s’ from archive-forums. That template part doesn’t exist, thus http://www.example.com/forums/ returns empty. (Also themes that don’t have support for bbpress don’t display anything for /forums/ url – is this default functionality?)
Thanks.
