Fatal error after migration

Parse error: syntax error, unexpected T_STATIC, expecting T_STRING or T_VARIABLE or ‘$’ in /x/content/x/x/html/wp-content/plugins/better-font-awesome/better-font-awesome.php on line 134

URL is http://microclinics.org

Lines 125-138 below. As opened in Sublime Text 2, this is the line causing the error: $instance = new static( $args );

/**
* Returns the instance of this class, and initializes the instance if it
* doesn’t already exist.
*
* @return Better_Font_Awesome The BFA object.
*/
public static function get_instance( $args = ” ) {
static $instance = null;
if ( null === $instance ) {
$instance = new static( $args );
}

return $instance;
}
