Facebook API Error

[Phphag]

I connected to Facebook API everything is worked well, till I got this error:

Fatal error: Uncaught OAuthException: An active access token must be used to query information about the current user. thrown in /xxx/base_facebook.php on line 1271

Can someone please advise.

What do you want to know?

What this error occur? What’s the common reason?

[JimL]

Well, the error say you need an access token, so I guess you have to create an access token…

I created an access token and used it, but it didn’t help.
Someone ever saw this error?
