OneClick Form Lite

User guide (short and practical).

Quick start

[oneclickform]

Form fields

A honeypot field is included to reduce bot spam.

Translations are included for FR, ES and PT-BR (English default).
The front-end form and the settings screen follow your WordPress Site Language (Settings → General → Site Language).

Recipient

Set To email to the mailbox that should receive messages.

Sender

Set From name and From email (used by the selected transport).

WP Mail

Uses WordPress wp_mail(). Fast to set up, but deliverability depends on your hosting provider.

SMTP (recommended)

Uses your SMTP server for better deliverability. Fill host, port, encryption, username and password.

Tip: many providers require an “app password”.

File mode

Writes messages to files for debugging or non-email environments.

Test email tool

Use the “Send test email” section to validate delivery and configuration.

Create a reCAPTCHA v3 key pair in Google reCAPTCHA admin and add your domain(s).
In the plugin settings, enable reCAPTCHA and paste the Site Key and Secret Key.
Keep the default action (contact_form) unless you changed it in your integration.
Set a threshold (commonly 0.5) and adjust if you block too many real users.

reCAPTCHA v3 is score-based (no checkbox challenge). Low scores are treated as suspicious.

No emails received: try SMTP, check spam folder, verify “From email” and recipient.
File mode not writing: ensure wp-content/uploads/ is writable.
reCAPTCHA blocks too much: lower the threshold or verify keys and domain.
