SITE IS DOWN, 404 loading DOM

I wrote to support 11 hours ago but still waiting.
Yesterday my site went down and now when I try to load it I get:

This happened after I moved some code form a code block on the main page to the project settting > body end section.

I moved it back but the issue did not resolve.
I removed it completely and still no.

This is the code:

<script>
  $(document).ready(function() {
    console.log('dom loaded')

 
    $('#emailSubForm').submit(function(event) {
      console.log("Form is submitted");
      event.preventDefault();
     
     
      const source = encodeURI("https://opsmachine.co")
     
      let email = $('#subFormEmail').val();
     
     
      let input = {
          id: 223, // Your REST API Request ID
          properties: [
              {key: 'email', value: email},
              {key: 'source', value: source}
              // Add other properties here
          ]
      };

      mdActions.ItemGet('REST').Fn('run', {}, input, (success) => {
          console.log(success); // Will return {success, message, data}
        },
        (error) => {
            console.log(error); // Will return {success, message}
      });
    });
     
  });
</script>

<!-- <script>

  // Wait for DOM to be fully loaded
  document.addEventListener("DOMContentLoaded", function() {
    const submitButton = document.querySelector("#emailSubmitButton");

    submitButton.classList.add("g-recaptcha");
    submitButton.setAttribute("data-sitekey", "reCAPTCHA_site_key");
    submitButton.setAttribute("data-callback", "onSubmit");
    submitButton.setAttribute("data-action", "submit");
    console.log("recaptcha init")
  });
 
  function onSubmit(token) {
    // Assuming the button is inside a form element
    console.log("submitting")
    document.querySelector("#emailSubForm").submit();
  }
</script> -->

Can anyone tell me how to reach support (other than support@divhunt.com)
And what is in place with Divhunt for when this happens?

I’m not sure how long I should expect a response but for a website host I would think much faster?

Updated, I’m told my main page was no longer the root ( / ) path so this explains the issue but not how it occurred as a result of the actions above.

Will update for posterity.
