Thanks for the credentials. I just logged in. The issue is that JLinked is no longer compatible with JFBConnect. Once JFBConnect v6.x is used, JLinked should be removed.
To fix, I disabled the JLinked Authentication, Content, System and User plugins. With that, things started working again.
If you haven't already gone through the
JLinked Migration
guide, you should now. That will import your LinkedIn connections from JLinked over to JFBConnect and you should be able to safely uninstall JLinked completely.
I hope that helps, but if you need anything else, just let me know.
Thanks,
Alex
