Facebook plugin error

Hi everyone,

I downloaded in january this plugin : “Facebook” version 1.4 by facebook,
Now everytime i log in my website it gives me this error: “evalInSandbox:Error: Permission denied for <https://www.facebook.com&gt; to create wrapper for object of class UnnamedClass” , it shows 4 times in a row, and “Error: Permission denied for <https://www.facebook.com&gt; to create wrapper for object of class UnnamedClass”

it shows both when i am logged in as administrator and when i am not,

Anyone has any idea on how to fix it please?

🙁

thank you

Francesca
