Problem with submitting a form through Contact Form 7, how to fix it?

Question

JavaScript

Hello! The problem is this: there is a landing page landing.upsound.org/pesnya-pod-klyuch , when submitting data through a form (any form on the site), the icon of rotating arrows appears, but nothing happens. And this problem is only in Chrome, in other browsers everything is fine. But even in chrome, every 5-6 attempts it works, and everything goes as it should. Tried with different computers, the problem is the same everywhere. I would really appreciate your help! What could be the problem?

Answer 1

1. Start with a simple check carefully all the fields in the email template settings. Are all fields appropriate and correctly named.
2. Look at the mail settings, how do you send mail. If you use the SMTP plugin and Google account, for example, try setting up sending via Yandex mail.
3. If firewalls are installed, temporarily disable while testing the site.
4. If it's really bad, copy the form code, remove the plugin and install it on a new one, create a form with a new name and upload everything again. If it doesn't work, install the plugin for sending mail through the Mailgun service.
It is important for you to understand what the problem is, in the mail services or in the form itself.
When loading the site, you do not have the cast_sender.js script, carefully look where it is and why it is not visible to the site.
And if you use hosting in your panel settings, enable a newer version of PHP, you have 5.3, which is a rather old version.
