find
wp-content/plugins/bbpress/templates/default/bbpress/content-single-forum.php
transfer this to your pc and edit
find line 45
<?php bbp_get_template_part( 'form', 'topic' ); ?>
and delete this line and save
create a directory on your theme called ‘bbpress’
ie wp-content/themes/%your-theme-name%/bbpress
where %your-theme-name% is the name of your theme
Then transfer the file you saved above and put in in the directory called bbpress that you created above, so you end up with
wp-content/themes/%your-theme-name%/bbpress/content-single-forum.php
bbPress will now use this template instead of the original
