Nathan Pinno on "[Plugin: BuddyPress Group Tags] Error that needs solving please."

I'm getting this error:

Warning: Missing argument 2 for wpdb::prepare(), called in /home/uff/public_html/wp-content/plugins/buddypress-group-tags/bp-group-tags.php on line 170 and defined in /home/uff/public_html/wp-includes/wp-db.php on line 992

Can you please fix this error soon?
