I am having this exact same problem. Does anyone have any other ideas?
I have already been running my dev environment as a vhost with a fake domain, and I followed the rest of the advice in this thread as closely as possible. However I am still getting a brand new session on each page load. I can't even get it to work with an actual domain in a staging environment.
If anyone has any other helpful advice, it would be very much appreciated. Thank you.
