Remove foote bar

Hi Carlos, you can add this CSS:

.site-info {
    display: none;
}

This snippet should work as well:

add_action( 'after_setup_theme','tu_remove_footer' );
function tu_remove_footer() {
    remove_action( 'generate_footer','generate_construct_footer' );
}

Adding PHP: https://docs.generatepress.com/article/adding-php/

Thank you

Glad we could help :)
