OmniMarkupPreviewer 404

[emettely]

Hello,

When I open OmniMarkupPreviewer on Firefox, this is displayed:

Error: 404 Not Found

Sorry, the requested URL 'http://127.0.0.1:51004/view/31' caused an error:

'buffer_id(31) 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.

I have Python 2.7.6 This is what it says in the console:

OmniMarkupPreviewer: [INFO] Launching web browser for http://127.0.0.1:51004/view/31
OmniMarkupPreviewer: [ERROR] Exception occured while rendering using MarkdownRenderer
  Traceback (most recent call last):

    pairs = [x.split("=") for x in ext_args.split(",")]
    File "./markdown/__init__.py", line 234, in build_extension
  UnboundLocalError: local variable 'module_name' referenced before assignment

Please help!

Also having this issue, same console output (within local variations).

I faced this today, just change the port, it seems another server is already using it. Go to Preferences -> Package Settings -> OmniMarkupPreviewr -> Settings - User and change the port:

{
    "server_host": "0.0.0.0",
    "server_port": 9998
}

that should work.

I'm pretty sure that is a solution to a different issue. The main problem here is the traceback being produced in the console, not the error message the page produces. Changing the port number does not fix this issue (at least on my machine).

Follow @pahko 's advise, my st2 on Mac OSX works. The key thing is to change the "server_host" to 0.0.0.0, rather than "server_port". I don't know the root cause. But who cares? it work~. (-_-|||)

I've install another Sublime package "Markdown Preview" before, it seems they are in conflict. I solve this problem UnboundLocalError: local variable 'module_name' referenced before assignment by Package Control: Remove Package -> Markdown Preview It works for me.
