I solved the problem of ‘no links to create child theme’ in a different way=>.
I am using Customizr with WP 3.8.1. I have discovered that in using the Child Themify plugin, that the ‘Create a Child Theme’ button does not appear under each theme on the Themes page unless I have at least one other theme installed.
So, once you have activated the theme of your choice, DO NOT delete ALL of the other themes. Leave one extra theme in the Theme library. That being the case, you can then click on the ‘Theme Details’ button of the activated Theme and the Child Themify plugin button, ‘Create a Child Theme’, will appear at the bottom of the Theme Details page with the other theme detail option buttons.
I preserved the 2014 Theme, I did not test whether this problem was theme specific to Customizr.
I hope this helps.
