1) New post links in the forumhome goes to the .php page rather than .html.
e.g. http://www.daniweb.com/techtalkforum...hread2379.html link takes you to http://www.daniweb.com/techtalkforum...4318#post14318

2) In the online.php? page, if the visitor (a google bot) is looking at a specific posts in a thread, e.g. http://www.daniweb.com/techtalkforum...08#postid=8308
it shows up as a .php? rather than a .html

but all other threads show up properly as .html. So only when a member or a visitor is at a specific post, the link in the online.php? page shows up in such a way.
