Thanks, catacaustic. Obviously I added too much information to this post. Basically, my question is about the correct syntax when nesting php code within an opening-closing do_shortcodes. The nested code is part of the buddypress activity/index.php, what I’m trying to achieve is wrap the ‘user activity’ elements showing on the page within a row element shortcoded by Shortcodes Ultimate plugin.
eg.:<?php echo do_shortcode( “[su_row] nested buddypress activity/index.php code [/su_row]”); ?>
