Adding Generator For Single Prefab Structures

[xoft]

Ah, you need proper configuration for the GalExport's web interface to appear. I think there should be a message in the log about it, when starting the server.
You should have a GalExport.example.cfg file next to the server that has an example config. This is my config, use it as basis for yours:

Config =
{
	CommandPrefix = "/ge",
	ExportFolder = "GalExports",
	ExportLineEnds = "\r\n",
	WebPreview =
	{
		ThumbnailFolder = "GalExportWeb",
		MCSchematicToPng =
		{
			HostName = "blackbox",
			Port = 9998,
		},
		MCSchematicToPngPort = 9999,
	}
};

Note that you need the WebPreview secvtion to enable the web handling, and for that, you need the MCSchematicToPng daemon to be running somewhere accessible. https://github.com/madmaxoft/MCSchematicToPng
