A week ago my transactions email were working just fine, but today they aren't. Since they were working I changed the email address they are being sent from, I've created my own templates and assigned them, and I got a new paymentgateway Epay. I think the problem may be the paymentgateway. I if look into my system.log i find the following error;
2014-09-28T11:23:25+00:00 CRIT (2): Not valid template file:adminhtml/base/default/template/epay/standard/email.phtml
Can this be the problem?
