prestashop category / subcategory make cms 404 error - prestashop-1.6

Question

I am working with prestashop in a local environment and then set up a store, the problem that I have emerged is the following.
Buy the module to remove the IDs of URLs: Module Pretty URLs and works perfect.
then I want to show the URL of the subcategories the category parent, example: example.com/women/jeans
that achieve it using the following code, modifying the file override/classes/dispatcher.php
'category_rule' => array(
'controller' => 'category',
'rule' => 'categories:/}{rewrite}',
'keywords' => array(
'id' => array('regexp' => '[0-9]+'),
'rewrite' => array('regexp' => '[_a-zA-Z0-9-\pL]*', 'param' => 'category_rewrite'),
'categories' => array('regexp' => '[_a-zA-Z0-9-\pL]*'),
'meta_keywords' => array('regexp' => '[_a-zA-Z0-9-\pL]*'),
'meta_title' => array('regexp' => '[_a-zA-Z0-9-\pL]*'),
),
),
In the Prestashop admin adding {categories:/}{rewrite} to the SEO/URLs of the categories.
file override/classes/Link.php
public function getCategoryLink($category, $alias = null, $id_lang = null, $selected_filters = null, $id_shop = null, $relative_protocol = false)
{
if (!$id_lang) {
$id_lang = Context::getContext()->language->id;
}
$url = $this->getBaseLink($id_shop, null, $relative_protocol).$this->getLangLink($id_lang, null, $id_shop);
if (!is_object($category)) {
$category = new Category($category, $id_lang);
}
$params = array();
$params['id'] = $category->id;
$params['rewrite'] = (!$alias) ? $category->link_rewrite : $alias;
$params['meta_keywords'] = #Tools::str2url($category->meta_keywords);
$params['meta_title'] = #Tools::str2url($category->meta_title);
$selected_filters = is_null($selected_filters) ? '' : $selected_filters;
if (empty($selected_filters)) {
$rule = 'category_rule';
} else {
$rule = 'layered_rule';
$params['selected_filters'] = $selected_filters;
}
$cats = array();
foreach ($category->getParentsCategories() as $cat){
if (!in_array($cat['id_category'], array(1, 2, $category->id)))//remove root, home and current category from the URL
{
$cats[] = $cat['link_rewrite'];
$params['categories'] = implode('/', array_reverse($cats));
}
}
$r_url = $url.Dispatcher::getInstance()->createUrl($rule, $id_lang, $params, $this->allow, '', $id_shop);
return $r_url;
}
But to do this all the pages CMS throw me a 404, not that it can be.
