PHP Fatal error: Call to a member function getSubCategories

[patrmich]

Hi,

 

My shop is built with Prestashop 1.5.6.2.

 

On a error log file on my server, I can see the following error about 10 times a day :

PHP Fatal error:  Call to a member function getSubCategories() on null in ../controllers/front/ProductController.php on line 551

 

On the line 551 of the ProductController.php file is : 

 'subCategories' => $this->category->getSubCategories($this->context->language->id, true),

This line is part of the following code :

// various assignements before Hook::exec
        $this->context->smarty->assign(array(
            'path' => $path,
            'category' => $this->category,
            'subCategories' => $this->category->getSubCategories($this->context->language->id, true),
            'id_category_current' => (int)$this->category->id,
            'id_category_parent' => (int)$this->category->id_parent,
            'return_category_name' => Tools::safeOutput($this->category->name),
            'categories' => Category::getHomeCategories($this->context->language->id, true, (int)$this->context->shop->id)
        ));

I am not a developer and I do not know what could lead to this error.

Would you have any idea of what could make this error ?

Thank you in advance for your any reply.
