Hello, LambdaSP,
Thank you for your response.
1/ You need to test if the problem persists when CDN is disabled. CDN is not a part of our theme, so we can’t do this for you, we would recommend you to contact your hosting provider.
2/ Also, ask your hosting provider to check if there have been any breaches to your website.
3/ Describe the full situation to the hosting, you can provide the URL of this topic – https://www.8theme.com/topic/i-have-problem-with-the-images-in-my-website/#post-355088 and ask to check the problem with images from their side too.
We hope it is clear now.
Kind Regards,
8theme team
