Markdown folding does not work with minimal setup

[ryantuck]

Markdown folding doesn't work for me out of the box. I am guessing I am missing something obvious, but I've read through the readme and nothing is jumping out at me.

I get E490: No fold found when hitting zc hovering over a header in visual mode:

settings

Reproduce with the following ~/.vimrc (after having called :PluginInstall):

set rtp+=~/.vim/bundle/Vundle.vim/
call vundle#begin()

Plugin 'gmarik/vundle'
Plugin 'godlygeek/tabular'
Plugin 'plasticboy/vim-markdown'

call vundle#end()

And vim version 8.1:

$ vim --version
VIM - Vi IMproved 8.1 (2018 May 18, compiled Sep 16 2018 18:20:26)
macOS version
Included patches: 1-400

Have you tried zX to recalculate folding? It works for me everytime, but still, an annoying problem.

Same problem in Mac as well. zX doesn't solve it.

I had the same issue and, in my case, was caused by vimwiki configured to use markdown. It appears there is a conflict so check if this is a plugin you are using. Also worth troubleshooting by disabling any other plugins with markdown functionality.

This doesn't apply to all users, but in case you're using vim-polyglot, here's why folding doesn't work: https://github.com/sheerun/vim-polyglot/issues/478

I've you're using Vim's built-in Markdown syntax file (check :scriptnames), then you'll need to :set foldmethod=expr.
