Facebook not posting anymore!

Dear support,

It’s not posting to facebook anymore.

I receive this message when i reautorize my facebook:

Reported Error: (#100) Tried accessing unexisting field (access_token) on node type (User)

And when i submit a testpost to facebook i receive also this message:

Array ( [pgID] => [isPosted] => 0 [pDate] => 2014-04-09 11:20:44 [Error] => Error validating access token: The session has been invalidated because the user has changed the password. )

The user has changed the password?? I changed nothing and it is still my old password.

Please help.

Thank you
