Do you check the products one by one to see if the cheapest combination is active? If the online store has 10 products, I'll still pass it on to you, but if you have 1,000 products or more, imagine the time you're going to invest. This is not going to be a problem anymore, I have programmed a free module for PrestaShop that will do this job for you.
The module will go through all the products and all their combinations, and apply the cheapest combination as the default combination. Comment that this module is valid for PrestaShop 1.6 and 1.7.
