Hi,
When I check your site, it looks like you have the preloader enabled, this is why the site is white with a spinning icon for a few seconds, you can disable this in the theme settings. Enfold Theme Options ▸ Page Preloading
When I check your page with Safari on a Mac the background video is working for me.
I do see this console error only in Safari: Unhandled Promise Rejection: AbortError: The operation was aborted. but it doesn’t keep the video from playing for me. I found this stackoverflow thread about the message.

Best regards,
Mike

Hi,
Try this CSS in your Enfold Theme Options ▸ General Styling ▸ Quick CSS field:

  margin-left: 6px;
}

Hey rixi,
How much smaller do you want them to be on mobile? Currently they are 100% width for mobile. Please see the screenshot in the Private Content area.

Hi,
Glad that this helps, we have not seen this request before, and what it might cause for users that don’t use Yoast as I don’t see a check in the code for the plugin.
If you would like to request this feature the Dev Team has opened a new Github Feature Request for users to place requests and follow them as the Dev Team reviews them.
In the meanwhile, shall we close this thread?

Best regards,

Hey Lion Speer,
Your version is very old, you will need to update, but since then Envato (Theme Forest) has changed from a API to a Token, so first you must manually update.
To update your version of Enfold you will need to download the latest installable WP version from your Theme Forest account and upload it to your WordPress ▸ Appearance ▸ Themes ▸ Add Themes ▸ Add New

after you choose the zip file and click install, you will see a This theme is already installed message because you are updating, you can continue

then you will see the Theme updated successfully message.

Best regards,
Mike

Hi,
Thanks for your patience, please add this css with Ismael’s
Please note that testing with iPads & iPhones can be hard to clear the cache, often you need to also clear the history to fully purge the cache, following these steps for Safari and note Step 4 where you will Clear the History.

Hi,
Your sub-sites show multiple errors: Failed to load resource: the server responded with a status of 500 ()
This looks like a config error on your webhost.

The HTTP 500 Internal Server Error server error response status code indicates that the server encountered an unexpected condition that prevented it from fulfilling the request.
If you’re a visitor seeing 500 errors on a web page, these issues require investigation by server owners or administrators. There are many possible causes of 500 errors, including: improper server configuration, out-of-memory (OOM) issues, unhandled exceptions, improper file permissions, or other complex factors.

Try asking your webhost to review your multisite config, it is not something that can be fixed inside of WordPress.

Mike

Hey dondela,
Thanks, I added this to your child theme function.php

function move_cookie_consent_modal_buttons() { ?>
  <script>
var copyDiv = document.querySelector('#av-consent-extra-info .avia-cookie-consent-modal-buttons-wrap');
var appendtoDiv = document.querySelector("#av-consent-extra-info .av-special-heading");
if (!!copyDiv) {
    var clone = copyDiv.cloneNode(true);
    copyDiv.style.paddingTop = '25px';
    appendtoDiv.appendChild(copyDiv);
}	   
  </script>
  <?php
}
add_action( 'wp_footer', 'move_cookie_consent_modal_buttons', 99 );

Please check.

Hey Sylvain,
You can use the layerslider with a transparent header like this: https://kriesi.at/themes/enfold-2017/
or the fullscreen slider with a transparent header like this: https://kriesi.at/themes/enfold-2017/elements/fullscreen-slider/
or add the image as a background image color section: https://kriesi.at/themes/enfold-2017/elements/color-section/
this is another color section example with a transparent header: https://kriesi.at/themes/enfold-2017/pages/blank-pages/coming-soon-page/

Mike
