Support » Plugin: Really Simple CAPTCHA » Number of characters in captcha

  • Hi,

    I am trying to increase the number of characters in the chaptcha under the function”
    public function __construct()

    I tried to change 4 to 6 at: $this->char_length = 4;
    And also change 72 to 100 at: $this->img_size = array( 72, 24 );

    The number of characters changed well, but the size did not change, so part of the captcha was not visible, how to fix this?

  • If you use with ‘Contact Form 7’, then you need to change the file \plugins\contact-form-7\modules\really-simple-captcha.php#580, change the img_size of switch case ‘s’ or ‘l’ or ‘m’. Thx.
