I didn't actually do anything, it just suddenly stopped giving me 0's and started posting the actual score. I believe the Facebook API was being updated, or was down for maintenance or something at the time I was initially testing.
I found a few little bugs like that which seemed to fix themselves - I think Facebook are always making changes to their API and it just causes little niggles. Nothing we can do about it really!
I had the same problem making the Facebook plugin itself - it's very frustrating, sometimes it doesn't work but if you come back a few hours later it just works again. Facebook are notorious for being annoying like that with their API, just something we have to put up with unfortunately.
Hey rockhoggie, could you please share which permissions did you have to correct at Facebook? I'm going through this "Score: 0" problem too!
Edit: I got this part, I hadn't set it to Game category on App Details over there at FB.
Now the score is correct for each submission, but it doesn't seem to be writing anything anywhere: the rank position is always #1, and the list does not get organized by anything other then when it was posted - each submission will go to the next line regardless of the score being submitted's points.FluxGameStudio2012-11-26 20:14:11
