After Upgrade 4.10 Core Files Changed And Old Product Variations Issue

After I upgraded to 4.10, it showed two warnings:

1. Some of your core files where changed manually.

layouts_lite_checkout_multivendor.xml although we didnt change any files.

2. Your store still has old product variations. They currently appear as separate products, without the ability to switch between them. To make them work as before the upgrade, convert old variations to new variations. It's easy and automatic.

When I click on covert old variations, it redirects me to a page "Converting products into variations" and it says: "No data for conversion found: it appears that your store doesn't have option combinations or product variations." :?

1. Such things happen. You can skip this notification.

2. So do you have products with option combinations or product variations ?

I have products with options like size and color

I have products with options, after the update if an option is chose, other than the standard option, it is not possibile to add the product to the cart.

I have tried everything but does not work. I had to de activate ALL options for the time being without knowing when the issue will be resolved.

Check for yourself the issue on my website, I have left 1 article with options: https://lanternevolanti.com/normale-piccolo/

Add the candle to the product and you will not be able to add the combination to the cart.

Options do not mean combinations or variations. They had to be created separately

I have products with options. These options were created separately. You can choose a product and as an option you can add other products to the chosen product.

After last update the options do not work anymore

Did II do something wrong? How can I solve this??

Please check PM

Not sure if we really do have products with variations, but when I click on convert old variations to new variations, it says there are no product with variations.

You said that you have options. But did you create combinations or variations by these options on the previous CS-Cart version?
