That may well be the reason, but what is the solution?
surely bbpress needs to send commands to wordpress such that it produces the desired result, i.e. selecting a navigation link in a bbpress widget should navigate to the desired page in bbpress, not jump to some random news page.
If it’s fixed in 2.4 as indicated above, that’s great but that’s not released yet.
Only thing is that is a global limit for both the widget and the main forum display and I’d like to have more showing when viewing the forum than when viewing the widget on the front page, is this possible (maybe calling a custom version of the form)?
