My help isn’t much help because I haven’t really found a solution. The good news is that you are not alone:

https://github.com/webtechnick/CakePHP-Facebook-Plugin/issues/43

What I can tell you is that the facebook cookie (fbsr_{facebook_app_id}) is either not deleting or is being recreated and that is the root of the problem.

EDIT

I may have found out what’s going on here. Until the other night I had not bothered to setup my .htaccess files and both http:/www.example.com and http:/example.com were valid.

In my facebook app, I had set up example.com as a domain and pointed the site URL to http://www.example.com.

With the fbsr_{app id} cookie, I noticed that it was sometimes on the http://example.com while my cakephp cookies were on www.

I played around with changing the URL in my facebook app (adding www, removing www) and then also started doing the rewrite rules in .htaccess to add or remove www. I just removed the appdomain entirely from my facebook app, forced www. to the domain, and now everything is kosher.

So I think the trick is to

1. Not have the app domain in the facebook app
2. Fix canonicalization of www via .htaccess

This ensures that both the cakephp and the facebook cookies are being saved to the identical domain, and when you logout they are removed from said domain.

Hope this makes sense…
