@terratag after looking over the server logs and tested the optimization results I saw that images are already optimized and our image optimizer cannot improve the image.
Enabling auto optimization will test all images and do the following actions:
– ignore subsizes that have .webp. Example:
/wp-content/uploads/2021/03/product-school-dJICd7b_LlE-unsplash-768×576.jpg
/wp-content/uploads/2021/03/product-school-dJICd7b_LlE-unsplash-768×576.jpg.webp
– send to optimization main image:
/wp-content/uploads/2021/03/product-school-dJICd7b_LlE-unsplash.jpg
see that image cannot be improved and return -7

And move to the next.
With current coding there is not a test main image, to see if optimized version exists

How many images do you have?
I have a way, I tested it on one of my sites, to skip all images before a specific image.
There is this code, here: https://pastebin.com/60DvwvR3 that can be added to a php file( name it: image.php) on root of your site ( https://your-site.com.au )
It contains a xxxxxxx that need to be replaced with the id of latest image optimized.(You can find the ID from media galllery)
Example: if latest is 122, write 122

Then run the script by visiting: https://your-site.com.au/image.php

In image optimization tab should write: Current image post id position: xxxxxx
This mean the code run correctly.
Now send images to optimization and see how it behaves.
If something goes wrong, please do not click on Destroy All Optimization Data It will delete all optimized images. Instead click on Soft Reset Optimization Counter that will reset the last id optimized without removing data.

I tested the site from our CDN node near you(direct access was limited by Geographic block)
Litespeed cache plugin settings are looking good
But header for cache-control is no-cache
Please check if your theme do not contain some code that changes headers.

@terratag thank you
This helped 🙂
This is not an error. Before sending image to optimization, LSC will test if image need optimization. This is done by searching for image_name.webp (webp in your case).
I saw you had ShortPixel Image Optimizer enabled.

I think that the images were optimized(by LSC OR other plugin) and the optimized images are still on disk.
It will send 1 image at once until it get image to optimize and increase the limit.
Did you tried to optimize images with LSC before?(I ask to know how to further help you)

@faradei a fix was added to DEV code.
You can test it from LSC => Toolbox => Beta Test
Click on dev then on update
Clear cache and test the code.
Caution: this is a dev code, there are known issue in it, but ESI part can be tested.

This mean that the fix will be added in a future versions of LSC.

Thank you!

@studioviv
What value you have selected for: https://docs.litespeedtech.com/lscache/lscwp/pageopt/#load-js-deferred ?

You disabled cache setting from LSC?

@sureshramasamy nice!
Can you help by telling what was the issue?

@infinitee to fix the issue you will need to exclude some JS from combine/minification
https://docs.litespeedtech.com/lscache/lscwp/pageopt/#js-excludes You will need to identify which is the culprit.

@mc1969 please send a report to Litespeed and share the ID generated(just the ID)
Here is how to send report: https://docs.litespeedtech.com/lscache/lscwp/troubleshoot/#get-a-report-number
