Hi, I have to solve similar problem..
After installing the theme, to edit it with the Child theme I did not consider to add anymore on style.css usuall @import but i added on functions.php the function:
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );
function theme_enqueue_styles() {
wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}
but nothing, just corrupt theme on WP control panel..
Then i discovered i wrote on style.css file, Template: Tracks instead of Template: tracks with lowercase t , and no more corrupt theme.
I activeted the child theme and.. 500 internal server error!!
Anyway, now i fixed this problem reinstalling after deleting tabels on mySql.
That is final, the function on functions.php, do i have to change something or this is the code??
And if i have another css called style.min.css , what i have to do??
Thanks!!
