I’m wanting to create a child theme for our GovIntranet installation. I have set up the minimum WordPress requirements for a child theme (folder created, style.css file with requisite comment). I can see it as an available theme in the WordPress Manage Themes page. When I activate the child theme in the WordPress Manage Themes page I get an internal server 500 error on any page of the site. I tried adding a blank functions.php file. Same error message. I am able to fix it by using a MySQL GUI to change the theme back to the original. I have tried enqueuing the parent style.css and the style.css from my child theme in functions.php and get the error as well. Is there something else I need to enqueue?
I am running GovIntranet Theme Version 4.27.4 and WordPress version 4.6. PHP 7.05 on Windows Server 2008R2 using IIS 7.5.
