If you’re a WordPress user and use BBPress to run forums (like mine), you’ll probably notice the subforums display uses commas and looks a little messy. If you don’t mind editing a PHP file, it is fairly easy to fix and display as a block list instead.
You would need to FTP into your site, and browse to /wp-content/plugins/bbpress/templates/default/bbpress and edit the file loop-single-forum.php.
Do a search for the line < ?php bbp_list_forums(); ?> and change it to < ?php bbp_list_forums( array ( 'separator' => ' ' ) ); ?>.
Save the file and re-upload it to the server. Once you refresh your forums page you’ll see the change. That’s all there is to it!
