About a year ago I created a tutorial on my website showing step-by-step on how to configure your own Xibo CMS installation. This was all based on a CentOS 7 server running Apache.
I found some free time on my work to upgrade our server, which was running Xibo 1.7.7. We upgraded it to Xibo 1.8.9 which is the latest stable version.
The Upgrade guide can be found here.
The old set-up guide can be found in this thread on the community forums.
I will do my best to answer your questions, but cannot guarantee my full support!
Good luck and thank you for being an awesome community!
