eg..:
showing correctly on: https://api.coala.io/en/latest/Developers/Newcomers_Guide.html
not showing: http://docs.coala.io/en/latest/, http://docs.coala.io/en/latest/Users/Tutorial.html

seems its only applied on api.coala.io not on docs.coala.io

Closing this on account of opened issue in wrong repo and some issues already started to be worked upon in the correct repository.
