Plugin installs but doesn't work or install shadow tiddlers

[LunaEqualsLuna]

I'm trying to install the Railroad plugin.

However when I install it and try to use it, it says "undefined widget railroad"

It says its installed but none of the shadow tiddlers it requires get installed so I'm guessing this is why its not working?

What do I need to do?

As an added note I'm currently hosting my own tiddlywiki on ec2, so its not a local version.

It sounds like you didn't save and reload after installing the plugin. The shadow tiddlers won't look like they are installed until you do that. If you have saved and reloaded than check in the control panel under plugins to make sure you have enabled the plugin.

Thanks I reloaded and now the shadow tiddlers look installed but I now get another error.

Everywhere where railroad is supposed to render a diagram it gives:

TypeError: Parser is not a function
