I installed odoo 9 on CentOS 7 on a remote server.  I was editing the website page and now that I try to go to my database selector or ip:8069/web/login page I get internal server error.  

My pg_hba.conf file looks like this:

local samerole all md5

host samerole all 127.0.0.200 255.255.255.255 pam pamservice=postgresql_cpses

host samerole all 127.0.0.1 255.255.255.255 md5

local all postgres md5

host all postgres 127.0.0.1 255.255.255.255 md5

When I type in my ip:port I get my website and I can see products and the main page, but cannot access my apps such as sales, purchase website admin, etc...

This is what it looks like:

How do I fix this?
