OK so I added the Session Value in that tab (see screen shots). Is that all I need to do? I uploaded the updated page, as well as the helper php file that appears to have changed. I cleared my cookies for this site, logged in while checking the auto-login feature. I then logged out and returned to the home page. Same blank screen, not correctly showing the userlevel show region as before. Feel free to use the login I provided earlier to verify from your end.
Do I need to do something on the "Database" tab on the Authenticate User tool? What else am I missing?
