LiteSpeed’s server (quic.cloud) for image conversion and optimization are sometimes overloaded. This can cause a delay in optimization and conversion. If there are any problems, check the current status at https://status.quic.cloud/

Hello Pedro,

Thank you for your kind reply and for clarifying the possible inconsistencies. I have to emphasize that I only know the Shortpixel plugin and how it works to a very limited extent. So I can only follow logic and very limited methods for image conversion. It should also be noted that neither you nor I can know the actual situation on @ben72’s server. This inevitably leads to the wrong conclusions being drawn if one does not know the exact situation on the affected server. This does not necessarily make it easier to investigate errors and causes.

If @ben72 now says that he deactivated the webp replacement function in the LiteSpeed cache plugin, then the cache plugin logically has nothing to do with the occasional display of webp images. Then, in case of doubt, only the cache can play a role. However, this only applies if the shortpixel plugin changes the source of the tag and the file extension at the same time, depending on the browser support for webp images. If that were the case, then the Short Pixel plugin would be incompatible with the LScache plugin because it would require additional and differentiated cache vary in the .htaccess.

However, you say that the webp images would not even be written to the file system. There is actually no logical explanation for this, especially since the cache plugin has no influence on the wp-content directory. However, it does affect the loading of Javascript or AJAX requests. Therefore one (you) would have to clarify whether the AJAX process you mentioned actually only runs in the backend.

If we can’t find a solution, the plugin support would have to deal with it. I’m only an authorized LiteSpeed Support Partner.

You can use CSS to hide this hint.

Do you use cache plugin function for image optimizing?

Would a plugin like EWWW work with LiteSpeed?

The problem is repeated with every other plugin because none (except mine) is compatible with LiteSpeed cache plugin. The only exception are plugins, which leave the source code unchanged and do not create the images on-the-fly.

Which I only see now when I looked at the source code of your site. Shortpixel changes the source of the <img> tag. This is disastrous if Shortpixel does not also define the appropriate cache vary for it. This means: If you call up an uncached page with a browser that supports webp, then the page called up will be cached. If you call up the same page with a browser that does not support webp, then this browser gets webp images loaded, although it does not support this format at all. This means that this user will not see any pictures.

Then it’s probably like I said, that Shortpixel sometimes creates the images on-the-fly. But it’s not the fault of the cache plugin if the image conversion doesn’t work. Rather, it means that Shortpixel is not cache friendly.

So the problem can only occur when a page is cached and you add or change images.

Why has it stopped? Did something change in LiteSpeed or ShortPixel?

No, I think it was pure coincidence because the methodology hasn’t changed.

This has nothing to do directly with the toolbox. If your server was already on the verge of overloading, then your server was overflowed by the toolbox’s request. This would probably have happened to you with every other page in the backend. You should get a stronger server because it is foreseeable that your frontend will also be affected by the overload.

In principle, however, you should contact your hosting provider in the event of an overload. He can help you better in such matters.

If it works now that can only mean that the UCSS code is regenerated. So I wouldn’t count on it staying that way forever. If the problem occurs again, delete the cached UCSS code or/and use my code.

Have you tried to regenerate missing images?

Images in webp format don’t exist on your server:

This could be because your server is overloaded, at least at the moment.

If images are not loaded there only 2 possible causes:

1. Source code in HTML Code is wrong

or/and

2. Image doesn’t exist.

The images at the given URL don’t exist on your server.

I’m glad to have helped you. ??

What do you mean by that?

If you have access to the .htaccess, please do what I asked you to do.

Assuming you are right when it comes to the generation, I don’t understand why this would stop working all of a sudden? How can you explain that?

The need for PHP for image conversion has never changed. It’s the same as needing air to breathe. It would be helpful if you would post a link to your site. Then it would be easier to identify the problem.
