Key must be less than 56 characters and non-zero. Supplied key length: 64

I’m trying to get started with CS Cart and when I click “Place Order” for a credit card purchase I get the following error:



Key must be less than 56 characters and non-zero. Supplied key length: 64



At first I thought perhaps I couldn`t place test orders until I had configured the payment gateway. Now that I’ve configured the store to work with Authorize.net (correctly, I believe), I get the identical error anyway.



Has anyone ever seen this or know what causes it?



Thanks.

this is the encryption key in your config.local.php
