I've seen the Foreman Versions 1.2.1.x and 1.2.0.x, when installing via packages from the RPM repository using SCL

When enabling support_jsonp support via the foreman settings.yaml the rails app fails to start with an error complaining about the version of rails not being installed on the system. If set to false the foreman app starts without issue.

[root@puppet foreman]# sudo /etc/init.d/foreman start
