UltiSnips 2.2 does not works

Check the mappings: imap <tab> for example (if you did not change anything).

It sounds to me that the script in ftdetect/ is not properly sourced. Are you using vundle or any other plugin manager?

yes I have such imap.
My scripts:

  6: D:\vim\Plugins\UltiSnips\ftdetect\snippets.vim
  7: D:\vim\Plugins\UltiSnips\ftdetect\UltiSnips.vim
 78: D:\vim\Plugins\UltiSnips\plugin\snipMate_compatibility.vim
 79: D:\vim\Plugins\UltiSnips\plugin\UltiSnips.vim
 96: D:\vim\Plugins\UltiSnips\after\plugin\UltiSnips_after.vim

:(.

1) What is the output of imap <tab>?
2) Are you using vundle or any other plugin manager?

i <C-Tab> * <C-R>=UltiSnips_ListSnippets()<CR>
i ø * <C-R>=UltiSnips_JumpBackwards()<CR>
i ú * <C-R>=UltiSnips_ExpandSnippetOrJump()<CR>

I use Ycm that is why I don't use tab I use <A-z>.

I use custom plugin manager.

BTW <C-Tab> also does not work. As well as :call UltiSnips_ListSnippets(). I don't think it is a problem of mappings at all.

I downloaded the last version everything the same.

My setup is on https://bitbucket.org/WscriChy/vim-configuration/src. It is pretty cumbersome, but mb it could help.

I sent the master brunch. But it is old. I use develop.

Well, I still think that ftdetect/UltiSnips is not detected. Have you tried the lorem<tab> snippet? Also, what happens when you use UltiSnipsAddFiletype python

does class<tab> do anything then?

Also, ycm comes with support for ultisnips out of the box, so if you start typing lorem, ycm should suggest a completion for this snippet right away.

Is it possible because of new vim runtime (7.4.83)?

very unlikely - I use a very recent version of Vim head and do not have any problems. You will need to try a minimal version of a .vimrc and only ultisnips and see if that works.
