CDN via Cloudflare for websites hosted at SiteGround, it this possible?

If you're having SiteGround as your hosting provider you cannot properly set Cloudflare and use it as a CDN together with ShortPixel Adaptive Images. This is because of a technical limitation of the SiteGround-Cloudflare integration.

However, you can still use ShortPixel Adaptive Images but with the "out-of-the-box" ShortPixel CDN.
