Hi,

Just after clearing the cache, cookies and site data its working ones and after then its making the some problem again (see video)

Hi,
we have made other test, and now something is not working. Strange!!

we think of two possibilities:
- FB app not configured properly
- Problem with session configuration

to find the problem we need to have FTP and backend access. is also necessary to know whether it is a site in production or not.

Hi,
we are sorry but we did not understand the problem, fortunately, we have produced a workaround.

we did many tests but it's impossible to reproduce this thing:
- different jquery versions
- different FB app
- different template
- enable/disable System Plugins

for some strange reason, if a user is already logged on facebook, then the system makes a redirect (to request access token) on the wrong window (chrome tab). This happen only on your site !!!!

We have produced a workaround on file /plugins/jsn/socialconnect/socialconnect.php, in the next release we will include this fix.

Hi,

So you Can't fix this problem?

Thanks,
Eitan

Yes we will fix in next release.
