How do I upload the Norton Authentication File to the root folder of my website? Thank you!
Wix Support would have answered that for you.

GivemeWhisky,
Thank you! I was able to add the Meta Tag, saved and published. But when I went back to Norton to Verify my site, I got the verification failed message. 
I submitted my question to the Norton User Forums and rec a reply that this will be corrected.
