Re: Disable “Latest Discussions”
bb-templateskakumeifront-page.php (or the same template name in any alternate theme you might be using) and find the line that says
<?php if ( $topics || $super_stickies ) : ?> (around line 11) and make it say
<?php if ( 0 && ( $topics || $super_stickies )) : ?>
which will make the if statement always fail and never show the latest discussions. If you ever want to restore it, just remove the zero &&.
