Magento

I can not add configurable products to the compare list

Which setting must be changed so that it is possible ? Or can the customer just compare simple products ?

thanks in advance

I have the same issue, and I’m not sure there is any way to compare a configurable product with any other product.

Is it because the prices of the products are diffrent ?

In the last released version 0.8.17240 configurable products can be added to compare list.
