I am facing a very strange error message on checkout level on our Magento 2.4.4 instance with products with quantity below 1 and this only for customer group "Not logged in"

When checking out only an article with 0.5 units I get an error message saying "Some of the products are disabled"

Error message: Some of the products are disabled

But those products are all enabled in all our store views.

For those products o.5 is the minimum quantity, as they are a material, which can be bought in units < 1 and also in decimal quantities.

In our store I have the MOQ set as 0.5 globally for each customer group and then Quantity uses decimals = Yes

MOQ 0.5

I can put the article with 0.5 into the shopping cart without problem.

But when I say "Proceed to checkout" with only 1 article with 0.5 int the cart, I get the error message as stated above.

Strangely when I put 2 articles with 0.5 into the cart, I can checkout without any problem.

Only quantity below 1 creates a problem.

Does anyone know how and where this error message can stem from, even if the products are enabled?

  • may be you have set wrong value in Enable Qty Increments and Qty Increments textbox.

  • may be it is magento2.4.4 bug. compare Magento\Checkout\Model\GuestPaymentInformationManagement ::savePaymentInformation function with old magento version.

  • just remove (int) from if (!(int)$quote->getItemsQty()) { Line num: 179 it should be if (!($quote->getItemsQty())) {

1 Answer 1


check your magento file vendor/magento/module-checkout/Model/GuestPaymentInformationManagement.php

the GuestPaymentInformationManagement.php file is updated in magento2.4.4 version.


replace below code and check.

 if (!(int)$quote->getItemsQty()) {
            throw new CouldNotSaveException(__('Some of the products are disabled.'));


            throw new CouldNotSaveException(__('Some of the products are disabled.'));

    Unfortunately all values in Minimum Qty Allowed in Shopping Cart , Qty Uses Decimals, Enable Qty Increment set correct. Minimum Qty Allowed in Shopping Cart = Use config settings as above Qty uses decimals = Yes Enable quantity Increments = No Things is, that it works with logged in users but not with user group = Not logged in

  • Genius! This worked smooth like a knife through soft Amul butter :) Amazing. Additonal question: can it be that this already also needs to be changed when putting item to cart? Because there already we got a similar error message. When we double clicked that worked.
