Sorry for getting back to you so late Ben. I just want to confirm before we move forward; The others that are logging in have selected a stream and are still unable to get past the profile page?
The error log you have posted here are just notices. They shouldn’t prevent anything from happening. Can you take another look at the logs and see if there are any fatal errors? I don’t suspect that there are any because I have replicated your scenario and don’t see any. Reply with some of this information and I will keep hunting a solution for you.
