Which Prestashop version are you using? Also let enable your developer  mode to check error on that blank screen.

 

To enable developer mode.

 

To enable developer mode, you need to edit defines.inc.php file in /config folder.
 
Search
define('_PS_MODE_DEV_', false);
and replace it with
define('_PS_MODE_DEV_', true);

Above solution should also work for you. Try editing PageNotFoundController.php file, search for Tools::redirect(); and add below line after it.

Tools::redirect(); // added code to redirect customer to homepage rather than to 404 page.

 

Let us know if you need further assistance.

Hi Dorje,

 

I developped a module that automaticaly add a redirection on product or category deletion (for products, categories or blog posts you will delete in the future). 

For the products you already have deleted, it's more experimental but you could configure it to add a redirection (unactive) when a 404 error occurs and then choose the ones you want to activate (because the url looks like a product one or because the url has been requested many times for example). 

 

Hope it helps,

 

Yann

@knowband

yeah above code works fine for some urls but not for all.  IT doesnt work for disabled products. 

Also the redirects are 302 not 301 , so i want the 301 redirection. 

i did check the code and replace the 302 to 301 but still the same redirection code shows which is 302 

 

ex check the redirection code for these url

http://www.kathmanduclothing.com/module/mailalerts/actions?process=add

http://www.kathmanduclothing.com/en/wholesale-tops-for-women/155-ssd-701-.html

 

"if (Tools::strtolower(substr($matches[2], -8)) != '_default')

                {
                    header('Location: '.$this->context->link->getImageLink('', $matches[1], $matches[2]), true, 301);
                    exit;

 

Also some of the disabled product urls which does not redirects. Please check them 

ex http://www.kathmanduclothing.com/woolen-hats/22-gb-64-.html shows 404 

http://www.kathmanduclothing.com/nepali-scarves/50-sh0680-.html

and too many 

but in 1.6 x we can redirect it manually one by one to another related products which is very time consuming, so i just want to redirect all disable products to either their categories or to homepage. 

 

Any help would be very much appreciated.

I did it this way:

 

File:

/override/controllers/front/PageNotFoundController.php

 

Code:

class PageNotFoundController extends PageNotFoundControllerCore
{
	public function initContent()
	{
		parent::initContent();
		header('HTTP/1.1 301 Moved Permanently');
		Tools::redirect('index.php');
	}
}

Dont forget to delete cache/your class_index.php file after you put file in override folder. A new file will automatically be generated next time you visit site
