You must enter in Advanced Parameters -> Performance and on "Combinations" item, check Yes and Save. You will se that now you can add to cart. Similar to this, I have manualy changed the value to "false" on "PS_COMBINATION_FEATURE_ACTIVE", direct from phpMyAdmin in "configuration" table .

On my database that parameter was null, I updated it to false and the error report dissapeared. Thanks for the clue.

It works for me. I got this problem today second time and problem gone  when I set the Combination to Yes.

First time I have a modified index.php it was one line from PhpMyBackup and this was a case of the error.

Wonderful, thank you so much. A switch from "null" to "false" in ps_configuration, PS_COMBINATION_FEATURE_ACTIVE totally saved the day.

Hello,

 

better and the CORRECT way is to change the classes/Carrier.php on line 1389

 

from

            if ($cart_product['weight_attribute'] > 0) {
 

to

            if (isset($cart_product['weight_attribute']) && $cart_product['weight_attribute'] > 0) {
 

 

and like this you can disable Combinations for better performances
