This sounds like an issue with either markdown or grip. Are you using any of the optional flags? Can you confirm that markdown or grip is installed?

I've installed plasticboy/vim-markdown for syntax highlight, and have no idea with grip....

Please view this module's Requirements. You'll need to install a small module that renders markdown files to HTML. Let me know if you have any questions or issues regarding this process.

It works!
Thanks! It's my fault...
