Hello Alex,
Unfortunately that is not the cause of the issue. The javascript error is new (we are testing some other things on a new module).
Anyway, I have added a menu point that will open the JFBConnect Facebook login in the Beez template.
Exact same symptoms as I described :
When logging in to the website, without being logged in to either Facebook or Joomla, the Facebook login button conects me to facebook (in the background), does not return any errors, but then just stays on the login page without logging me in to Joomla. Clicking the facebook login button over and over does not do anything, I have to refresh the page first and then I can click the login button again to be logged into Joomla.
Now for the even more interesting part :
Doing the same as above : not logged in to joomla, not logged in to Facebook, click the login using facebook button. provide credentials. I am being logged in on facebook in the background, but again not in joomla. Again, clicking the login to facebook button does not do anything. This time instead of refreshing my joomla page, I open a facebook window and log out of facebook on the facebook website.
Now I return to joomla and hit the login using facebook button again. I get the popup to provide my facebook credentials, and put them in there and click ok.
Now, I get an error message! I click ok on the error message, and facebook opens in the login popup - I am not logged in to Joomla.
Thanks for having a go at this
