I did some further tests.
The problem is in my child theme in the function php file.
The line that causes the problem is:
wp_enqueue_script(‘general_js’, get_stylesheet_directory_uri() . ‘/js/general.js’, array(‘jquery’));
-when I delete it evrything works fine.
-when I keep it but delete the content in general.js file the problem still hapandes.
I understand it’s not under your Area of ??responsibility so unless the answer is simple and fast for you I thannk you for the great support!!
