Hi
Every time anyone opens checkout page, the same errors appears:
PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘custom_override_default_address_fields’ not found or invalid function name in /home/letterli/public_html/wp-includes/class-wp-hook.php on line 286
PHP Warning: uasort() expects parameter 1 to be array, null given in /home/letterli/public_html/wp-content/plugins/woocommerce/includes/class-wc-countries.php on line 710
I already deactivated one by one the plugins to be sure if one of them was having troubles and i still get this warning.
The checkout page crashes from time to time, many clients says that it just stucks on loading.
I fond out that it is theme issue, but I couldn’t find the solution.
Please, help
.
