[ymart]

Dear all,

I have Magento 2.1.7. and after I've included some products on my wishlist. I clic on  "Add all to cart" button, the page is left blank and the URL shows the following address: http://url_base/wishlist/index/allcart/?qty[5]=1&qty[6]=1

Help!

Hi @ymart,

Is possible you're getting an error 500 on your server.

Please take a look to your Magento logs, reports and also the webserver error log.

Dear @Damian Culotta

Thank you for you reply.

In filelog I found the followin messages:

Last  lines of    Only show lines with text     

And the Item.php line 482:

public function getBuyRequest()
    {
        $option = $this->getOptionByCode('info_buyRequest');
        $initialData = $option ? unserialize($option->getValue()) : null;

        if ($initialData instanceof \Magento\Framework\DataObject) {
            $initialData = $initialData->getData();
        }

        $buyRequest = new \Magento\Framework\DataObject($initialData);
        $buyRequest->setOriginalQty($buyRequest->getQty())->setQty($this->getQty() * 1);
        return $buyRequest;
    }

Could someone see what the problem is?

Hi @ymart,

Can you try setting the LUMA theme again and try that action?

[ymart]

Hi @Damian Culotta

Yes I did .. I still have the same problem with Luma 

[Damian Culotta]

Are you using some 3rd-party modules?

[ymart]

Hi @Damian Culotta

No, I'm not using 3rd-party modules
