E117: Unknown function: <SNR>69_ReadTodoKeywords

[athanassis]

Hi,
I have installed vim-orgmode with pathogen and python 3.10.7.
I get this message for the unknown function ReadTodoKeywords. The function seems to be used or defined in these files:

thanos@win10-ubuntu:/mnt/c/Users/adamis/vimfiles
$ grep -ril ReadTodoKeywords *
bundle/vim-orgmode/syntax/org.vim
bundle/vim-orgmode/syntax/orgagenda.vim
bundle/vim-orgmode/syntax/orgtodo.vim
pack/git-plugins/start/vim-orgmode/syntax/org.vim
pack/git-plugins/start/vim-orgmode/syntax/orgagenda.vim
pack/git-plugins/start/vim-orgmode/syntax/orgtodo.vim

Any pointers what could be the problem?

Ran into the same issue multiple times and just now decided to dig a little deeper.

My environment is:

• Arch Linux
• vim 9.1
• plugin manager: vim-plug
• installed plugins and their git-describe:
  • NrrwRgn e027db9
  • ale 699c0db
  • calendar-vim 2083a41
  • nerdtree 7.1.3
  • tabular 12437cd
  • tagbar 8de7694
  • taglist 97b001b
  • utl.vim 3.0a-ALPHA
  • vim-SyntaxRange 78004d2
  • vim-colors-solarized 528a59f
  • vim-markdown 8f6cb3a
  • vim-orgmode 8398234
  • vim-repeat 6584602
  • vim-speeddating c17eb01

I found that the global variable g:loaded_org_syntax seems to be the culprit. It is nowhere else referenced than in syntax/org.vim, so I removed it alongside with the exists() check:

This seems to do the trick. However: I have no idea whether or not somebody else would rely on g:loaded_org_syntax.

@jceb, could you comment on that? How bad of an idea would this be?
