Some Optimole-optimised images become a single-colour rectangles

Hi @nazrinn,
Thanks for sharing the URL where the issue can be replicated. After taking a deeper look, it seems you are having this problem because of the litespeed lazyloading adding to the images.

If you are using LSCache plugin, please disable all media optimizations including lazy loading inside LSCache: https://docs.litespeedtech.com/lscache/lscwp/imageopt/

Then go inside the Optimole settings and enable the lazyloading via Optimole or use WP native browser lazy loading.

Disabling media optimization and lazy load via LSCache and instead lazyloading via Optimole will resolve your issue.

Honestly when using Optimole, you do not require any other plugin/system for media optimization as Optimole will take care of it all…

That did it. Thanks!

Hi @nazrinn,
Happy to hear that your problem has been resolved.
