THEMA: Number of friends in Facebook

Hello,
I got this message in my account:
"There are less than 5 friends listed in your facebook-account. At the moment 1 friends

Please fix that problem and click here:

update facebook-data"

I don't understand what is happening because I have friends in my facebook account. I click in the link "update facebook-data" and nothing changes.
Could you help me please?
Thanks
