background color wierd red

[JenTus]

Hi,

I'm using vim-wiki and the calendar.vim together. Thank you very much for this powerful plungin! My problem is, when I first run the :Calendar, the background shows the weird red. However, if I quite the calendar(:q) and run(:Calendar) again, the weird red background disappears. .

Here are my minimal .vimrc file regarding the color, vim-wiki and the calendar.vim. Thank you very much.

That looks like the color of trailing white space plugin. Do you have vim-trailing-whitespace plugin installed?
