sublimeText OmniMarkupPreviewer 404

这个错误也是出现的莫名奇妙。

"Error: 404 Not Found
Sorry, the requested URL 'http://127.0.0.1:51004/view/29' caused an error:

'buffer_id(29) is not valid (closed or unsupported file format)'

NOTE: If you run multiple instances of Sublime Text, you may want to adjust
the server_port option in order to get this plugin work again."

解决方案:

　　Sublime Text > Preferences > Package Settings > OmniMarkupPreviewer > Settings - User

 {
     "renderer_options-MarkdownRenderer": {
         "extensions": ["tables", "fenced_code", "codehilite"]
     }
 }
