Hi,
I updated my foreman setup to 1.14.2 yesterday. I'm running it on CentOS 7 and use your yum repository:

~ # rpm -qa | grep foreman
tfm-rubygem-foreman_hooks-0.3.13-1.fm1_14.el7.noarch
tfm-rubygem-foreman_column_view-0.3.0-1.fm1_14.el7.noarch
foreman-release-scl-3-1.el7.noarch
tfm-rubygem-foreman-tasks-core-0.1.1-1.fm1_14.el7.noarch
foreman-selinux-1.14.2-1.el7.noarch
foreman-1.14.2-1.el7.noarch
tfm-rubygem-puppetdb_foreman-2.0.0-1.fm1_14.el7.noarch
tfm-rubygem-foreman-tasks-0.8.6-1.fm1_14.el7.noarch
foreman-postgresql-1.14.2-1.el7.noarch
foreman-debug-1.14.2-1.el7.noarch
foreman-proxy-1.14.2-1.el7.noarch

The Web UI fails to load after the login due to some javascript files:
