Orion/Clearing local storage
Orion caches state in a relatively recent HTML5 facility called local storage. Most browsers don't currently have good support for clearing state from this cache when it is stale. Typical "clear history" or "clear cookies" options in your browser probably won't clear this state out.
Because Orion is very early in development, we sometimes have to make incompatible changes to our cached date. When you start using a new Orion build on the same server where you used an older build, it is recommended to clear your browser's local storage. The easiest way to do this is to navigate to the Orion server main page, and then type the following in your browser's location bar:
Hit enter, and the cache will be cleared.
