Hello

When I choose French langage, I've this error on the top of the page :

Warning: preg_match_all() expects parameter 2 to be string, object given in /home/wordpress/bitnation-wp/wp-includes/formatting.php on line 219

Warning: array_intersect(): Argument #2 is not an array in /home/wordpress/bitnation-wp/wp-includes/formatting.php on line 220
