Chanda,
In the future, it's best if you can post with the account you subscribed from. I found a PayPal payment from your domain under a user "Jonathan M." If that's your account also, or someone in your company, if you can post here from it, we can add your subscription to both accounts. That way, you can post from this account or the other one without hassle in the future.
As for your issue, the Login with Facebook button is showing just fine for me. Are you still having this issue? I checked both the home page and "My Clique" areas. The button showed in both (using Chrome) and looking at the HTML on the page, everything seemed right.
If it's still not showing for you, please try clearing your cache, just in case. It's possible it was a momentary hiccup on FB's part.. but who knows. We'll gladly help if you still have issues!
Thanks,
Alex
