Warnings while starting jekyll server

[k0va1]

I've added gem to Gemfile in group :jekyll_plugins. Everything works but why these warnings appears?

I believe this was because an earlier version of this gem was redefining a lot of the Document class for the sake of simplicity. It should no longer be an issue, please check.
