It's not working.
Here's what I did on another site:
- uploaded child theme; and added code to css file and the fuctions.php
- activated theme
- reconfigured all my menus and header area (the slate was completely wiped clean, had to put everything back)
- went to plugins area to upload new plugin (wordpress seo)
- went to homepage; all my menus disappeared and the welcome to dms! tour guide appeared.
Also when the child theme was activated all of my custom sidebars were messed up. Content that was supposed to be in column A was now in Colomn B and vise versa.
