Sign with facebook and linkedin have stopped working

The authentication worked for me. However, during the authentication, it looks like there is extension (likely for SEF) that is altering our authentication URLs. You'll need to disable that extension from altering our URLs. When it does so, they look like:
component/com_jfbconnect/1a8fde096da2676d226c3f3855611b67,1/provider,facebook/return,L2Vu/task,authenticate.login/view,login/

That's invalid and can cause some problems with the codes that Facebook returns to us.

I hope that helps get things fixed up,

I'd still recommend disabling whatever is altering the URLs as that could be the problem. Then, I'd suggest:
* Enabling Debug Mode in JFBConnect to see if any errors are output
* Testing from different computers to see if there is any difference in behavior.
* Testing from different accounts to see if there is any difference in behavior.

There really shouldn't be a reason it affects just one account, but hopefully the above helps narrow things down.

Thanks,

I'm not sure if the error_description at the end of the URL you post. There may be a conflict with the profile data you are trying to import and a recent change with LinkedIn. Yesterday, LinkedIn severely crippled it's API to only allow a very small amount of data to be retrieved for a user. We're planning a new release to support this update within the next few days.

In the meantime, I'd recommend going to the Profiles area in JFBConnect and checking the fields you are trying to import from LinkedIn. Remove (set to 'None') any of the fields that are not on this list below:
developer.linkedin.com/docs/fields/basic-profile

Keep us posted on how that goes.

Thanks,
Alex
