Error: Missing POST Data (access_token)

Works fine for my facebook sign in.

But getting emails with this error. (Bottom of post)
And have reports of someone unable to sign in as button greyed out.

Are there releated? Any idea what problem is with both?

Do I need to use the widget? Or can I just paste this code onto my page below my existing buddypress login form?


<fb:login-button scope="email,publish_stream" v="2" size="small" onlogin="jfb_js_login_callback();">Login with Facebook</fb:login-button>


Does it need to be inside a document.write script like in the widget?
Do I need to use <span class=”fbLoginButton”> or is this just for formatting?

Thanks for your help

Jon
