Where can we see the website in which you see the problem?

Good Morning,
Sorry, the website is under development, you cannot visit it.
I use the plugin with Contact Form 7.
Thanks

See Contact form in your language

Good afternoon,

All the template and plugins are shown in ES except Really Simple CAPTCHA.

I have uploaded a contact form to a public page:

https://www.autocontrol.es/autocontrol/contacto/

Thanks

The form on the page is en_US, not in Spanish.

All the template and plugins are shown in ES except Really Simple CAPTCHA.

Really Simple CAPTCHA is the image of four alphanumeric letters. It’s just a random choice. Not an English word.
