Can't get child theme to work

I hesitated to start new topic out of fear of looking stupid or lazy but nothing I do seems to help.

I activated child theme in admin panel (after i uploaded parent theme)
I renamed child-style-example.css into child-style.css
after i added custom css (moving widget column to the right), nothing happened

I copied entire base.css document from \blogs-mu\_inc\css to \blogs-mu-child\_inc\css and changed it and still nothing.

When i do the same css change in the parent theme it works, but I'd like to avoid that.

I even added the path of original css file ( @import url(../blogs-mu/_inc/css/base.css) to the child theme's style.css and still nothing.

I am out of the options :slight_smile: :slight_frown:
