For me, each of the network icons clicked properly after I clicked the "Allow cookies" option in the bottom. That allow cookies option never seemed to go away though. If you're having trouble, try disabling the cookie tool to see if that helps things.
I hope that helps, but if you need anything else, just let me know.
Can you try from different browsers and in different states of being logged into the selected network. I'm definitely seeing some problems with your app configurations:
* Facebook is indicating the App hasn't be set Live
* Github is throwing an error about your Redirect URI
* LinkedIn is throwing an error about your Redirect URI
All in all though, the code in JFBConnect seems to be redirecting properly. We'll need to narrow down why your system is behaving differently. Hopefully the tests above from different browsers or computers and being logged in (or not) will help determine the cause.
Well the Facebook you are correct that was not active. Now I tried also on another place but the buttons are not reacting. I don't get a popup. About the other that you mentioned I still have to look .
EDIT: Well out of the blue it wors now. Indeed a few are not connecting good so I have to look into those. Thanks!
Hmmm.. first, sorry for the delay in getting back to you. Next, I'm not sure what happened, but I'm glad it's working now. Not sure what would have changed or why, but obviously, keep an eye on things and let us know if you run into any issues.
