If I understand you correctly you want to amend a file in
wp-content/plugins/bbpress/templates/default/bbpress/
The easiest way is to copy the relevant file to your child theme
create a directory on your theme called ‘bbpress’
ie wp-content/themes/%your-theme-name%/bbpress and copy the file there eg
wp-content/themes/%your-theme-name%/bbpress/loop-forums.php
bbPress will now use this template instead of the original
and you can amend this
You can also add a location – for instance within a plugin I use I add a location using :
add_action( 'bbp_register_theme_packages', 'bsp_register_plugin_template1' );
//get the template path
function bsp_get_template1_path() {
return BSP_PLUGIN_DIR . '/templates/templates1';
}
function bsp_register_plugin_template1() {
bbp_register_template_stack( 'bsp_get_template1_path', 12 );
}
