[PRIME Theme] Contact form theme doesn't send messages

Hello,

Contact form doesn't send messages in this theme. When I click "Submit" button on the contact page, the page refreshes (form fields remain filled). Unfortunately, the author of this template is unreachable.

Thanks!

Hello,

First thing to check, have you configured the email plugin ?

Yes...I think so ;)
Email v2.6.0

Did you test the email with the CLI command?

No...but I the problem is with the template. The form isn't working properly.

You should create an issue on the GitHub repo of that project then.
