Hi,
I got an exception when inserting a code block into markdown. Below is the error message shown in python console:

OmniMarkupPreviewer: [ERROR] Exception occured while rendering using MarkdownRenderer
  Traceback (most recent call last):
    File "/root/.config/sublime-text-3/Packages/OmniMarkupPreviewer/OmniMarkupLib/RendererManager.py", line 266, in render_text
    rendered_text = renderer.render(text, filename=filename)
    File "/root/.config/sublime-text-3/Packages/OmniMarkupPreviewer/OmniMarkupLib/Renderers/MarkdownRenderer.py", line 36, in render

    if _alias.lower() in aliases:
  AttributeError: 'NoneType' object has no attribute 'lower'

This is the code block I added in markdown.

[PowerAdapter] -(Power)--> [Arndale] --(RS232)--> [LinuxHost]
                                |                    |

                                |                    |

Hmm, it seems the Evernote package uses a incompatible pygments, you can try to disable the Evernote package for now.

Oppss. It is fixed by removing the Evernote package. Thanks a lot.

Is there a way to fix this problem without remove Evernote package? I need both of the two packages a lot. I meet this error code when open README.md to OmniPackagePreviewer. Thanks
