This is a very nice theme but no support for a child theme.
The functions.php file in the Library folder needs modifying slightly.
Enqueuing all the scripts and styles has EVLJS but it is not defined anywhere....Why?
Add this line of code to the function evolve_media()
// I have added this to get it to work $EVLJS = get_template_directory_uri() . '/library/media/js';
Now change all reference to EVLJS to $EVLJS within the library\functions.php file
Mine is now working but not sure if anything else is needed but the theme is fixed...
