No errors, no data received

What other plugins and theme do you use on the site?

Hi, thanks for your quick reply.
Below is the list of activated plugins.
None have been recently added, all these plugins have been on the site for a long time.
Other forms on the website work. Such as here: https://viptaxipro.com/contact-us/
I hope you can solve the problem as to why validation seems to be failing when the only field needing validation is one email address.

Many thanks, Chris

Try switching theme to the default Twenty Nineteen or Twenty Seventeen and deactivating all other plugins.

Hi, that will kill the site.
Plus the theme and plugins have been in use for a long time.
Plus other Contact 7 forms on the site are working.

Working: https://viptaxipro.com/booking-system-registration/
Working: https://viptaxipro.com/contact-us/
NOT working: https://viptaxipro.com/website-setup/

Hope this helps

Best regards, Chris

This is a technique commonly used in WordPress to find what is actually causing a particular problem.

Switch temporarily (nothing will be lost when you switch back) to a WP default theme & disable all plugins other than Contact Form 7 to see if the problem goes away.

If it does you can switch back to your theme & re-activate each plugin one by one to see when the problem occurs.

Health Check is a good way to check this on a live site. It’s planned to be made part of WordPress Core in coming releases.

Hi,
OK, I have found the Plugin that is causing the problem!

I did not know about the Heath Check plugin which I have used to track down the problem – thank you, Neil.

If the plugin ‘Contact Form 7 Image Captcha’ is enabled, but an Image captcha is not used on that particular form, the form will show an error:
“One or more fields have an error. Please check and try again.”

I have added a captcha to solve the problem, but just because this Plugin is enabled, does not mean you MUST use a captcha on every form. It is bug IMO as previously this form has worked fine without a captcha but with the plugin enabled, as I use Captchas on other forms.

Regards, Chris
