hi,
The plugin use the default Buddypress Template, so if you use a child theme for buddypress, you must costumise the plugin template for your theme.
By copying /wp-content/plugins/buddypress-wall/includes/templates/bp-default/ to your WordPress theme you can override the template that comes with the plugin. The files template will be placed in the buddypress activity,groups and members directory.
9 template should be customised :
activity/activity-wall-loop.php
activity/entry-wall.php
activity/index-wall.php
activity/post-wall-form.php
groups/single/activity-wall.php
groups/single/home-wall.php
members/single/activity-wall.php
members/single/home-wall.php
For example, to update the activity/activity-wall-loop.php template,
open the template file in your favorite editor or IDE and open the template
activity/activity-loop.php (without -wall-) and replacing the template activity-wall-loop.php
by code from activity-loop.php and keeping only the bp-wall php code in the activity-wall-loop.php.
for example in activity-wall-loop.php, the
code
<?php bp_wall_load_sub_template( array( 'activity/activity-wall-loop.php' ) ); ?>
is used to load activity-wall-loop.php instead this code
<?php locate_template( array( 'activity/activity-loop.php' ), true ); ?>
used in the default buddypress template.
so you must replace the template content and keep the bp-wall script.
