CF7 not adding js and api to wp_footer

Hello,

I am using CF7 on a website. Unfortunately ajax is not working. It refreshes the page after submitting. I found out that the JS file, nor the CDATA part is being added, nor in my development site, nor in production with the full domain URL.

If I add the following manually to the footer, it works well:

  <?php wp_footer(); ?>
  <script type='text/javascript'>
    /* <![CDATA[ */
    var wpcf7 = {
      "apiSettings": {
        "root": "http:\/\/127.0.0.1:8000\/wp-json\/contact-form-7\/v1",
        "namespace": "contact-form-7\/v1"
      }
    };
    /* ]]> */
  </script>
  <script src="<?php echo get_home_url(); ?>/wp-content/plugins/contact-form-7/includes/js/scripts.js"></script>

It is not adding it nowhere. Nor in the pages with the forms, nor in other pages.
I tried to troubleshoot it the following way:
-I turned on twentynineteen – the same problem. Js. missing from the footer
-I turned on all other plugins, the same
-in production I have “Version 5.1.4” – in development I tried to upgrade it to the newest, but the same problem.
-running WordPress 5.2.1 and it cannot be changed

Any idea what else I can check?
