I'm using UserForms 4.6 with SilverStripe 3.7.2. Everything works except for the email actually sending and coming into the mail inbox. The form goes to the success page and the form data is saved in the CMS submissions just no email. I've made sure the from address is the same the domain. I get no error on the site.
I can see this 404 error in the cPanel logs: /UserDefinedForm_Controller/ping
How can I troubleshoot this?
