Hi,
I created a contacts page with the forms addon element, setup the variables for the form, and set the email recipient. No message is sent the recipient even though there is no submission errors posted. Additionally, there is no "send successful" feedback either. I have tried both; using a custom message in the Form Submit Success Message box and also leaving it blank so it would use the default message. Neither works but no error is posted either. If I do try to submit a message without filling in a required box, an error message is presented; so that functionality works.
I created a generic contact addon element and upon configuration, it sends message successfully so I know that the SMTP settings are correct and functional.
Regards.
