There's a theme that I want to customise and when I use a child theme in it's most basic form, the main navigation bar disappears, the fonts seem different and there's a few other oddities.
The problem theme is PR Pin (http://wordpress.org/themes/pr-pin). My child theme literally only has the style.css file containing my child them name, the template and the import of the parent theme's css.
/* Theme Name: Custom Theme for sallymustang.com (pr-pin) Template: pr-pin */ @import url("../pr-pin/style.css");
I don't know why activating the child breaks the parent when there's nothing changed.
