Same form on dev site with different them, form displays differently

Hi @srd75,

It looks like the production site was built using Elementor, while the development site uses the Divi page builder. On the production site, custom CSS code might be utilized.

You can follow the article here: https://ninjaforms.com/blog/single-row-wordpress-signup-form/ to create an inline form similar to the production site.

The following custom CSS is used on the production site to hide the second error message. You can use the same CSS code to hide the second error message.

.ninja-forms-req-symbol, .nf-error-msg.nf-error-field-errors, .nf-form-fields-required {
display: none !important;
}

Give it a try, and let me know how that goes!

Regards
Faisal
