I received a message that a site using WP may have been accessed and compromised.

It's unclear if there is a back up of the site's home directory, still looking into that.

Here's what appears at the site URL `startelecom.ca`

> 
> Warning: require\_once(/home/startele/public\_html/wp-includes/class-wp-menu.php) [function.require-once]: failed to open stream: No such file or directory in /home/startele/public\_html/wp-content/themes/StarTelecom2/header.php on line 24

Is there something in the code I can fix?

Thank you for your considerations.

Best regards,
