Upgrade to omnibus, can't create ssh key, or new project

I had a CentOS server running gitlab 7.2.0, which uses mysql
server. I updated to the omnibus version of 7.7.2 successfully porting
the database from mysql to postgres using instructions found here

Everything is working fine, except no one can create new ssh keys, or
new projects. Does anyone know why this would be happening, or how to
troubleshoot this?
