My child theme works fine with just the one file (styles.css) in the directory.
As soon as I add functions.php, it no longer works. Funny thing, even an empty functions.php or one with just <?php ?> and nothing more will cause the theme to fail.
How does it fail?
When you click on UPDATE, whether for adding posts/categories or editing, it returns a blank page. No errors. You just get a blank page. I've tried different browsers also just to make sure.
Anyone ever hear of this happening...and why?
