How could I fix this exception?
org.broadleafcommerce.core.workflow.WorkflowException: java.lang.UnsupportedOperationException: No currency conversion service is registered, cannot add different currency types together (EUR USD)
It happens when I order a product, when I click on accept button, after payment options (I choose collect on delivery). I think it has something to do with internationalization. Prices are shown in dollars, but the program may internally do some translation into euros. I haven't touched sql files. My computer has european configuration.
I'm using BLC 3.1.1. Any little help would be grateful. Thanks in advance.
