If you know how to use ftp, then
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 on your pc create a text file called content-single-forum.php and put the following contents into it
<?php
/**
* Single Forum Content Part
*
* @package bbPress
* @subpackage Theme
*/
?>
<div id="bbpress-forums">
<?php bbp_breadcrumb(); ?>
<?php bbp_forum_subscription_link(); ?>
<?php do_action( 'bbp_template_before_single_forum' ); ?>
<?php if ( post_password_required() ) : ?>
<?php bbp_get_template_part( 'form', 'protected' ); ?>
<?php else : ?>
<?php if ( bbp_has_forums() ) : ?>
<?php bbp_get_template_part( 'loop', 'forums' ); ?>
<?php endif; ?>
<?php if ( !bbp_is_forum_category() && bbp_has_topics() ) : ?>
<?php bbp_get_template_part( 'pagination', 'topics' ); ?>
<?php bbp_get_template_part( 'loop', 'topics' ); ?>
<?php bbp_get_template_part( 'pagination', 'topics' ); ?>
<?php bbp_single_forum_description(); ?>
<?php bbp_get_template_part( 'form', 'topic' ); ?>
<?php elseif ( !bbp_is_forum_category() ) : ?>
<?php bbp_get_template_part( 'feedback', 'no-topics' ); ?>
<?php bbp_get_template_part( 'form', 'topic' ); ?>
<?php endif; ?>
<?php endif; ?>
<?php do_action( 'bbp_template_after_single_forum' ); ?>
</div>
FTP this file to the directory you created above, so you end up with
wp-content/themes/%your-theme-name%/bbpress/content-single-forum.php
bbpress will then use this file.
