Error when payment option is COD

Hello,

I did submit a ticket on the Zorem site a few hours ago but as I am short on time I thought I would ask here as well. I love the Advanced Local Pickup plugin and I did pay for the PRO version but I am having an issue. Whenever I choose a COD option at checkout I get an error. The exact error is “Error processing checkout. Please try again.”. If I look on the backend I do see the order is actually in there but in a “Pending Payment” status even though on the front end it did not appear to complete. I am not sure what to do but it seems to me that it has something to do with the payment status. Please help.
