I'm pretty sure I'm responding to the correct thread since it's the only pgadmin thread I'm currently involved in.
I was asked to revert back to the default pgadmin httpd config to see if that fixed the issue, which it didn't. I posted the config I used and included some additional info in the event that it would assist in solving the issue.
I added the additional config option to the config_local.py and I’m able to login to pgadmin again.
