Getting a debug warning (added code from file in question)

Running WP 3.7
Collapse-o-matic v1.5.3

Black Box plugin (which shows debug info) is showing the Warning below on every page of the site. How do I remedy this?

Redefining already defined constructor for class WP_Collapse_O_Matic on line 61 in file /Applications/AMPPS/www/foo.org/live/wp-content/plugins/jquery-collapse-o-matic/collapse-o-matic.php
