[Plugin: Robots Meta] can’t activate plugin unexpected {

I have updated robots meta plugin to version to 3.0.9 but when it try to reactivate i get this error Parse error: syntax error, unexpected '{' in mysitewp-content/plugins/robots-meta/robots-meta.php on line 539
at this line there’s this code

function yahoo_verify() {
	if (is_home() || (function_exists('is_frontpage') && is_frontpage()) || (function_exists('is_front_page') && is_front_page()) {
		$options = get_option('RobotsMeta');
		echo '<meta name="y_key" content="'.$options['yahooverify'].'" />'."\n";
	}
}

How can i fix it?
