Hi,

i have experiencing for a while now a problem where if i login to my site via facebook. then open another tab and open the facebook.com url, i will then be looking at my facebook account etc and be logged in etc...

Now above is normal and expected. tab1(mysite logged-in),tab2(facebook,logged-in).

Now if i logout of tab2(fb) and then login as a different user in tab2(fb). then go back to tab1 and click around a few pages etc. the profile picture is updated with the new fb logged-in person. in other words my website gets confused and mixes profiles from 2 diffrent facebook users.

Another problem is that once this has occured if i say logout from tab2(fb) and then login with the matching user as tab1(site). tab1(site) will ask me to login with a user which is alreadly logged-in.

So i then have to delete the user via joomla and then create a new account.

i think jfb needs to actively listen as to weather fb is still logged in, from any other tab in the browser. when it detects a logout from any tab then it will auto logout of jfb site as well. Because 2 fb sessions cannot co-exist within a single browser at the same time.

i hope what i ahve put makes sense lol.

Many thanks in advanced

Phil,
I understand what your saying. There are a few things to note.. some which may be bugs, others which sound like something else..
When you logout of FB and login with a new user, if you navigate your site, the "mapping" between Facebook and your Joomla account should not be updated at all. This would be a huge security problem if so, so please check in the User Map area of JFBConnect if the joomla user and Facebook user mapping row is correct.

The above is regardless of the avatar that is showing. That could be related, but don't use the displayed avatar as information on what user is mapped.

Another thing that could possibly causing the problem is if you have a mixed domain site. Specifically, if you go to www.site.com and click around.. does your URL ever update to "site.com" (non-www)? If so, then there would be cookies for the both user's Facebook accounts placed on both domains. While there shouldn't be an update to the mapping, it could explain things a bit more. Mainly, if this is the case, then my guess is that user a is logged into www.site.com and user b would be logged into site.com (non-www).

Hope what I said makes sense. Mainly, focus on the user-mapping column for now. You really shouldn't ever have to delete users from your system due to JFBConnect's connection of them to their Facebook account.. if so, something is definitely wrong.

Thanks,
Alex
