I want to inform you of the following.
I have built Orion from source
I started Orion and followed the Reverse Text plugin example 
I selfhosted the site and installed the plugin.
After restarting the Orion server, the location of the selfhosted plugin is no longer there (188.8.131.52:8080
) which resulted in a blank client screen. Orion would not serve any UI.
After skimming through the workspace settings I found a json referencing this site and removed that line. After restarting the server the client started normally.
Let me know if I should file a bug for this.
