Base 64 GIF Code - 404 Error

Hello,

I’ve noticed an issue that seems to be connected to Rocket Loader according to another post here, but I’ve been unable to categorically confirm or deny this.

I have been trying to figure out why each image on my WordPress site is resulting in the following code being changed in all images I upload:

<figure class="wp-block-image size-large image-shadow img"><a href="https://www.example.com/blog-post-title/" target="_blank" rel="noopener noreferrer"><img width="600" height="400" src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-src="https://www.example.com/wp-content/uploads/2020/08/blog-post-title-image-1.jpg" alt="image description" class="wp-image-18844 lazyload" data-srcset="https://i1.wp.com/www.example.com/wp-content/uploads/2020/08/blog-post-title-image-1.jpg?w=600&amp;ssl=1 600w, https://i1.wp.com/www.example.com/wp-content/uploads/2020/08/blog-post-title-image-1.jpg?resize=300%2C200&amp;ssl=1 300w" sizes="(max-width: 600px) 100vw, 600px" /><noscript>

This results in Ahrefs scans displaying 404 errors for all URLs; for example, the URL below loads fine, but there is an added /images/gif to the string.

https://www.example.com/blog-post-title/

becomes

https://www.example.com/blog-post-title/images/gif

in the Ahrefs report coming from the crawl. It seems from what I have been able to find out that the issue may be coming from here:

src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7"

I host on SiteGround and use their CloudFlare addon with some settings applied through my CloudFlare account.

Has anyone else encountered these 404 errors? If so, may I ask how they were resolved?

I’ve experimented with various redirects to the post (which haven’t worked and maybe the completely wrong thing to do).

It seems that this issue was triggered by the JetPack Lazy Load settings. These have since been turned off and the issue has been resolved.
