indent_guides error / colorscheme issue

[foucist]

Got the following error:

Error detected while processing function 46_IndentGuidesEnable..indent_guides#enable..indent_guides#init_script_vars..indent_guid
es#capture_highlight:
line 2:
E411: highlight group not found: Normal

guides#capture_highlight:

Looks related to preservim/vim-indent-guides#31

Seems that colorscheme isn't getting loaded.

I added "colorscheme molokai_modified" to vimrc to force it. Fixes the error, but no colors?
