Hi Sebastian,
Thanks for writing in! Upon testing, I can confirm the WooCommerce featured image section is missing on your setup. It could be related to a plugin conflict as well, so could you please try disabling your 3rd party plugins except WooCommerce plugin and see if that resolves your issue. If the issue resolved, then you can activate your plugins one by one to see which plugin cause this issue.
Also I see that you have updated your WooCommere plugin to the latest version which could be another possible cause. Latest X/Pro compatible WooCommerce version is 3.5.1 as you can see it on our version information guide here (https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195). You can download the exact version from the following link (https://wordpress.org/plugins/woocommerce/advanced/) and downgrade your plugin.
With regard to your slider with YouTube video issue, I see that it’s not playing on your homepage and I see the following error on the console log.
Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘https://www.youtube.com’) does not match the recipient window’s origin (‘http://www.cafefolks.cl’).
So I have created a test page and see that your video is playing on load (see secure note for more information). You issue is similar to the following thread, so I suggest you to review it for further troubleshooting (https://theme.co/apex/forum/t/slider-revolution-youtube-video-will-not-play/12777/16).
Thanks!
