i had the sample problem, and i solved editing the anchor (<a>) link in views/forumlist/tmpl/default.php. In the anchor you see that can go to postlist o topiclist, delete the postlist option.

ALSO I HAVE A BIG PROBLEM WHEN YOU GET TO TOPIC LIST, AND LINK IN A TOPIC TO GO TO POSTLIST. tHE PROBLEM IS THAT DUPLICATE THE FORUM NAME IN THE URL.
