Problem with Facebook SDK in Editor

Let me get right to it.
I have a problem with the Unity Facebook SDK in the Editor. Everything works fine, even uploading screenshots, but the Feed function firstly gives the following error:

And then when I try to share I get 400 Bad Request error, and it does not event go to the callback function.

The Take & upload screenshot works perfectly well, so I’m sure I’ve setup my app correctly.

Thanks for your help in advance.

Try debugging your access token. I’ve found occasionally the tokens you get in the editor don’t actually contain all the permissions you requested.
