Answer 1

1) Try to add the

x_load('category'); 

in the include/common.php right after the

case 'C':

line

2) Try to compare your product.php with the default one and localize the problem.

3) Try to compare your include/common.php with the default one and localize the problem.

4) Try to compare your include/categories.php with the default one and localize the problem.

5) Try to move x_load('category'); before the code switch ($current_area) {

6) Try to add the code include_once $xcart_dir . '/include/func/func.category.php'; before the code switch ($current_area) {

Key notes:

• include/common.php was added in X-Cart 4.4.0

• The func_get_categories_list function is defined in include/categories.php file in X-Cart 4.1.9

• The func_get_categories_list function is defined in include/func/func.category.php file in X-Cart 4.4.0

• It will be helpful to define the exact version of your files for that compare files like include/func/func.core.php cart.php include/func/func.category.php include/func/func.order.php with the default ones.
