Child Theme Cannot Be Activated

I recently purchased the Orizon Theme and have tried to create a child theme for it. However when I try to activate the theme, I get the white screen of death and the whole website goes down.

I checked my error logs, and I’ve gotten warnings and fatal errors because WP is looking for required files in the child theme directory e.g.: PHP Fatal error:  require_once(): Failed opening required ‘xxxxxxxxxxxx/wp-content/themes/orizon-child/themeOptions/admin/options-framework.php’ (include_path=’.:/usr/share/pear53:/usr/share/php:/usr/share/ZendFramework’) in /xxxxxxxxxxxx/wp-content/themes/Orizon/themeOptions/functions.php on line 55

I checked the file Orizon/themeOptions/functions.php, and sure enough, it instructs WP to use the stylesheet directory to find the file themeOptions/admin/options-framework.php.

Apologies if I’m missing something obvious!

Many thanks,

Tom
