Hi Ofi,
I actually just redo everythig that I did before and also followed the video and the forum link you provided. I'm still getting:
An error has occurred.
0 Required "app_id" key not supplied in config and could not find fallback environment variable "FACEBOOK_APP_ID"
It use to work before and nothing has changed in our side after that but it just stopped working. I suspect it was caused by Admin Tools but I rember I already have admin tools enabled when this use to work before.
Could it be an update that you guys released?
Thanks,
Jackson
