I'm following the RHEL 7 guide for my first openstack installation. Everything is working really well with very few surprises, so props to the OP of this excellent guide!

When I installed and test Horizon I get a 500 error and the following apache logs. This looks to be a django environment issue with paths or permissions. It cant find the middleware modules. I've tried to find the path variable in the django configs but I cant figure it out. Could I get some hints on where to look next? This appears to be a pretty common issue with app builds, but this is the red hat horizon package itself.
