404 Error Handling: 0 - Using $this when not in object context

[kaiserdom]

I'm running Virtuemart 3.4.2 and when I click to link of a product that has been deleted, the system brings this error "0 - Using $this when not in object context" instead of redirecting to "404 Error-Product Not Found".

Virtuemart 3.4.2
Joomla 3.8.13
PHP 7.1.22

just tested here  -- I get a proper message

you need to turn on Joomla debug and full error to find where this error is

[kaiserdom]

Unfortunately I'm not a developer. Could someone please take a look at the link?

I'm receiving the existing errors

The code inside view.html.php

Code Select Expand

$product_model->withRating = $this->showRating = $ratingModel->showRating($virtuemart_product_id);
$product = $product_model->getProduct($virtuemart_product_id,TRUE,TRUE,TRUE,$quantity);
$this->assignRef('product', $product);

$last_category_id = shopFunctionsF::getLastVisitedCategoryId();

$customfieldsModel = VmModel::getModel ('Customfields');

line 81: if ($product->customfields){
$customfieldsModel -> displayProductCustomfieldFE ($product, $product->customfields);
}

they are only warnings/notices and 2 are not from VM

this has nothing to do with the subject of your post

Ok thanks.

[kaiserdom]

Is there a way to download VM 3.4.0 where everything worked just fine?

[kaiserdom]

It seems that the problem is coming from Virtuemart 3.4.2 «404 Error Handling». So I disabled it and created a custom Joomla 3.8.13 «404 redirection page».

Please use this package http://dev.virtuemart.net/attachments/download/1146/com_virtuemart.3.4.3.9973_package_or_extract.zip

Hello Max

Thank you for your help. This solution brings up the right message, but it redirects wrongly. The redirection page is something like a mix of non-found-product category view and product details view. Very weird.

[Milbo]

which is not possible. It should call the last correctly opened category

[kaiserdom]

For example, If I load https://www.mysite.com/products/category/product-detail the 404 error handling produces the proper message and redirects me to the same url https://www.mysite.com/products/category/product-detail and not the desired one which is https://www.mysite.com/products/category/. Thus the outcome is a weird page view. How can I omit the product-detail part on the redirections?

Anybody?
