@terabytesoftw how did you configure the Captcha ?

[terabytesoftw]

In the view:

<?php

use yii\bootstrap4\ActiveForm;
use yii\captcha\Captcha;
use yii\helpers\Html;

<?= $form->field($model, 'verifyCode', [
	'labelOptions' => ['id' => 'verifyCode'],
	])->widget(Captcha::class, [
		'template' => '{input}<div class="text-center">' . '<b>' .
				       $this->app->t('basic', 'Captcha Code') . ':' . '</b>' . '{image}</div>',
		'options' => [
			'class' => 'form-control',
			'oninput' => 'this.setCustomValidity("")',
			'oninvalid' => 'this.setCustomValidity("' . $this->app->t('basic', 'Enter Captcha Code Here') . '")',
			'placeholder' => $this->app->t('basic', 'Captcha Code'),
			'required' => true,
			'style' => 'margin-bottom:10px',
			'tabindex' => '5',
		],
 ])->label('<b>' . $this->app->t('basic', 'Captcha Code') . '</b>') ?>

In the model:

public function rules()
{
	return [
		// verifyCode needs to be entered correctly
		['verifyCode', \yii\captcha\CaptchaValidator::class],
	];
}
