Norton website verification failed

Good morning,

You are flagging us with a red x for one of our domains (plateautel . com).  I am attempting to verify our sites in order to re-scan, but it keeps failing.  I have added both the meta tag and the html verification file and it still fails.  Can you help me?  I need to get them verified so that we can re-scan these to remove the site warning.  It is affecting our bill pay site, causing customers to call in to us about the warning.  The domain we need to work on first is http:// www . plateautel . com, with sub-domains https:// billpay . plateautel . com and https:// appservices . plateautel  . com.  I have added the sites in question to our account here.  Can anyone help?

Thanks,
Keegan
