Hi again,
maybe I can add some more information:
When I try to use the Facebook-Code outside of JFB/Joomla by just directly opening the URL:
https://graph.facebook.com/me/xxxxxx-de:angemeldet?access_token=ACCESS_TOKEN&method=POST&emdr=http%3A%2F%2Fsamples.ogp.me%2F5xxxxxxxx128511
I get the error-message
{
"error": {
"message": "Invalid OAuth access token.",
"type": "OAuthException",
"code": 190,
"fbtrace_id": "xxxxx"
}
}
I am logged with the admin and the owner of the app.
I don“t know if this is connected, because I get no error-message and no log-entry in JFB.
All the best, J ulian!
