WP-Mega Menu Problem

So I installled Mega Menu on the Point Pro theme. The menu looks great but at the bottom of the site i see this:

Warning: strpos(): Empty needle in /home/content/p3pnexwpnas06_data01/02/2451402/html/wp-includes/media.php on line 1088

Warning: strpos(): Empty needle in /home/content/p3pnexwpnas06_data01/02/2451402/html/wp-includes/media.php on line 1088

When i deactivate the mega menu plug in it goes away leading to think it has to be something with mega menu. help please.
