1- ACTIVATING
What is the real use of activating or not layouts (apart not showing them under Layout Control)?

BUG: When deactivating THOSE layout = sidebar_varrious, home_parallax, home_presentation and home_jewelry, I get this error =

[PrestaShopException]

Property Options->column is empty
at line 909 in file classes/ObjectModel.php

904. }
905.
906. $message = $this->validateField($field, $this->$field);
907. if ($message !== true) {
908. if ($die) {
909. throw new PrestaShopException($message);
910. }
911. return $error_return ? $message : false;
912. }
913. }
914.
