Undefined variable: b:undo_ftplugin

[wolfv6]

This error displays at bottom of gVim when I open a markdown file: Error detected while processing C:\Users\wolf\vimfiles\bundle\vim-markdown-folding\after\ftplugin\markdown\folding.vim line:20 E121: Undefined variable: b:undo_ftplugin E121: Undefined variable: b:undo_ftplugin

I press Enter to continue and folding works fine. I am running Vim 7.4 with Vundle on Windows 7. This is in my _vimrc file:

set nocompatible if has("autocmd") filetype plugin indent on endif Plugin 'nelstrom/vim-markdown-folding'

Another plugin was conflicting with this one. Problem solved.

[nelstrom]

Which plugin?

Sorry, I changed many things in my vimrc file and can't reproduce the error now. Now I get this error at bottom of gVim when I open a .markdown file:

Error detected wile processing function 8_LoadFTPlugin: line 2: E184: No such user-defined command: FoldToggle

Here is my _vimrc file:

I had the same error code after installed the 'gabrielelana/vim-markdown' plugin.

I don't like the folding coming with 'gabrielelana/vim-markdown' as it is really a performance hit.
