basic captcha: no letters are displayed

[beamaria]

Hi all. I'm trying to implement basic captcha in my form. This is my form:

title: 'Contact Form'
form:
    fields:
        name:
            type: text
            label: Name
            validate:
                required: true
                message: 'Please enter your name!'
        email:
            type: text
            label: Email
            validate:
                type: email
                required: true
                message: 'Please enter your email address!'
        subject:
            type: text
            label: Subject
            validate:
                required: true
                message: 'Please enter a subject for your message!'
        message:
            type: textarea
            label: Message
            validate:
                required: true
                min: 10
                message: 'Email message needs to be more than 10 characters long!'
        basic-captcha:
            type: basic-captcha
            label: 'Are you human?'
            placeholder: 'copy the 6 characters'
            validate:
                required: true
    buttons:
        submit:
            type: submit
            value: 'Send Email'
    process:
        basic-captcha:
            message: 'Humanity verification failed, please try again...'
        email:
            from: '{{ form.value.email }}'
            to: '{{ config.plugins.email.to }}'
            subject: '[Contact] {{ form.value.subject|raw }}'
            body: '{{ form.value.message }}<br /><br />{{ form.value.name }}<br />{{ form.value.email }}'
        message: 'Thank you from contacting us!'
        display: /form/thankyou

But when I go to my contact form no letters are displayed:

I copied the documentation for basic captcha and I also tried to change the default values, but no success. Working with: Grav: 1.7.37.1 Admin panel: 1.10.37.1 Gantry 5: 5.5.15 Template by Rocket Theme

Still no solution after a month??? Forms are an essential part of a website!!

Well the problem is that it works for everyone else, just not you. Do you have PHP GD installed?

Hi Andy, thanks for replying. Sorry, what's GD? My PHP version is 8.0.26, but I can't find any reference to GD

Hi again Andy, I've found the source of the issue. I tried the code in MAMP environment, which evidently hasn't any GD enabled. Tried again on the online server and it works!. Thanks for pointing me in the right direction!
