• Yes, I tried minimal .vimrc configuraion.
• no, I have enabled logs with JCdebugEnableLogs and can put here content of JCdebugGetLogContent command, if you need. Never got this far.

I just realized that: pathogen, Vundle, NeoBundleand vim-plugwhere plugin-managers. My issue got solved after reading the Vim-plug manual, thanks.
