function error-crashed styles

Hi guys,
I’m trying to solve this problem for almost 8 hours. I duplicated my wordpress page – (shop, woocommerce, storefront child theme) with plugin called “duplicator” from let’s say localhost1 to localhost2. After successful transfer (no error during the proces).

I am constantly geting errors:

“Warning: call_user_func_array() expects parameter 1 to be a valid callback, no array or string given in X:\XXX_XXX\xampp\htdocs\wp-includes\plugin.php on line 235”

After long research I went trough my function.php file and started to coment-out one by one “add_XXX” functions and after I deleted this line:
“add_filter( ‘storefront_customizer_enabled’ , false );”
My poroblem disappear but I lost some of my styles on page.

What should I do to make it right ?

Kind regards,
Mikolaj
