Form Issues…?

Greetings! I am troubleshooting some errors for this website.

1) WordPress and all plugins are up to date.
2) The template is custom built, and plugins are hard coded into it.

The “Request Service” form uses a plugin called Fast Secure Contact Form.” I want to make sure the issue isn’t with the site itself, as there have been multiple errors in the template coding, and the plugin seems to be configured correctly. Personally, I use Ninja Forms…

So when you click “Submit” it just redirects to the Contact Page.

The form on the Contact Page does nothing- but it uses a different plugin which says “Front-End Form Submissions not Available in Free Version.”

Does that mean the form doesn’t work in the free version? What kind of version is that? Am I missing something?

Thanks in advance.
