I do not see any webp images served from WP-Optimize

Only newly added images are converted to WebP, are the images newly added?

For all images are webp images available on the server. e.g.:

https://ixtract.de/wp-content/uploads/2024/03/Header_Featured_Hompage_ixtract_6.jpg

So for every .jpg there is a .jpg.webp

So why does WP-Optimize not deliver the .webp images?

I do not know why, but today the site will be served from WP-Optimize with .webp images …

So I found the issue with missing webp images. WOP will never serve background images as webp, so this is why it seems to work sometimes and sometimes not.

Any idea how I can get sure that WPO is serving webp images for all background images, too?

Are you using a plugin to display your background images, how would I replicate your issue, can you do me some step by step instructions?

I suspect that we will need to look into this in more detail and that will involve us replicating your issue.

I just use Elementor, that’s all.

You can see it e.g. in the top row of images on the website. Here is a screenshot where you can see the image is placed in the background and is still delivered as .jpg while there is a .jpg.webp image available, which is not being displayed: https://imgur.com/a/2hZhYDy

Thank you for this, I will have a go at replicating the error on my site and then pass this onto our development team.

I see … any idea what can be done to temporarily fix it with any possible hook?

Having done some testing and having looked at your site, it doesn’t look like the issue is related to Elementor. None of your images are currently being served as WebP: https://snipboard.io/xBMdur.jpg

Having checked your network information, it looks like you are on a nginx server but under content type, I do not see WebP listed, please follow this guide to enable WebP: https://themify.me/docs/enable-webp-on-nginx-litespeed-servers

I’m currently working on the site so your testing was rong. Webimages are being served: <img decoding="async" width="1200" height="1200" class="lazy-load attachment-full size-full wp-image-8868 is-loaded" alt="AOK PPP Pharmacs PowerPoint Folien" sizes="(max-width: 1200px) 100vw, 1200px" src="https://ixtract.de/wp-content/uploads/2023/01/214_0674_AOK_PPP_Pharmacs_PowerPoint_Folien_1.jpg.webp" srcset="https://ixtract.de/wp-content/uploads/2023/01/214_0674_AOK_PPP_Pharmacs_PowerPoint_Folien_1.jpg.webp 1200w, https://ixtract.de/wp-content/uploads/2023/01/214_0674_AOK_PPP_Pharmacs_PowerPoint_Folien_1-150x150.jpg 150w, https://ixtract.de/wp-content/uploads/2023/01/214_0674_AOK_PPP_Pharmacs_PowerPoint_Folien_1-768x768.jpg 768w">

Enabling webp support from nginx will instantly reduce the page speed and show bad results in pagespeedweb.dev! This is why I disabled it.

Without nginx support, at least webp images will be served by WP-Optimize but not for background-images. AP Optimze seems a littly buggy, and there is no change to find the reason …
