Problems in the plugin

I installed the plugin in 2 different sites with 2 different templates and got the error message:
Warning: sprintf() [function.sprintf]: Too few arguments in /home/xxxxxx/public_html/wp-includes/nav-menu-template.php on line 226

No menu is shown.
Is there any correction to this problem?

Thanks 🙂
