Facebook Groups, Upload a photo: Invalid parameter (100, OAuthException)

Hi,
I want to make post with a photo in a facebook group.
I don’t know, what I have done wrong – also, because creating a post (without a photo) is working …




Any ideas? :thinking:

Best regards,
Martin

Hello Mr.Martin, Looks like your file name is with wrong extension, it should be jpg kr png…

:see_no_evil: You’re right.
Thank you very much.
