Module Facebook - Create a post with photos

Hello,
I’ve come to ask for a bit of help because since yesterday I’ve had a problem with my scenario and in particular with the “Facebook - Create a post with photo” module.

Since yesterday I’ve been getting this error at runtime:

DataError

Error: An unknown error has occurred (1, OAuthException)

Origin

Facebook Pages

I’ve tried to log in again, but to no avail.
I’ve just deleted my connection with Facebook, deleted the Facebook module and then created a new Facebook module in order to create the link between Make and Facebook again, but the error is still there.

How can I solve this problem?

Thank you in advance for your help and sorry for my bad English.
