Hello,
As I understand you get the error only if child theme is activated, right?
Then you need to check the code that you have in your child theme. I have made a quick look and see for example this code
if (!function_exists('etheme_shop_navbar')) {
function etheme_shop_navbar() {
return '';
}
}If you want to change the function in child theme there is no need to write if (!function_exists(
Try to change that code to
function etheme_shop_navbar() {
return;
}and check if the error still appears. If yes, then check the other code piece by piece to find out why you get that message.
Regards
