I’ve had your wonderful form working great on a site till I started using SSL on that site. Here’s the form https://beachsvr.com/great The firebug error I see is: Content Security Policy: Ignoring “https:” within script-src: ‘strict-dynamic’ specified
The form does not send email and also fails to catch blank required fields.
I see that others users in the Quform WordPress have had this issue but I can’t see their resolution because of my subscription.
This is [SOLVED] In the end, this was missing, EmailAddressValidator.php, and the common.php needed to be updated, and my smtp server settings needed changing. Thanks for your support!
