It doesn’t convert all images to webp and has an error displaying the original

Hey Eugenio,

Thanks for the report. I pushed a fix for this in the latest update.

Could you update the plugin and let me know if it’s working for you now?

Cheers

Hi Eugenio,

Thanks for URL.

All of them are working; however, only a few aren’t loading. For example:

https://cdn.staticdelivr.com/img/images?url=https%3A%2F%2Fvalorados.es%2Fwp-content%2Fuploads%2F2026%2F01%2F7363-cocina-para-todos-nuestro-viaje-a-traves-de-560-recetas-224×300.jpg&q=80&format=webp&w=224&h=300
This isn’t loading.
If you look at the original image:
https://valorados.es/wp-content/uploads/2026/01/7363-cocina-para-todos-nuestro-viaje-a-traves-de-560-recetas-224×300.jpg

It returns 404 on your website. Can you double check if the image does exist?

Looking at the Network Logs below:

You can see that all the ones returning 500 on the CDN have tried loading for up to 30 seconds on some cases. However, if you look at the screenshot below, the plugin does have a fallback system so that if there is a problem on the CDN it loads the original image on the original website, (bypasses the CDN).

By the looks of the network logs, the images may just be missing in your WordPress Media Library?

For example if you look at the thumbnail of your post, the image just returns 404 even with the plugin off. See here: https://valorados.es/category/iluminacion/lamparas-de-escritorio/

Let me know if that is the issue.

You’re right, Eugenio. These attributes are currently missing because of how the theme or editor handles images, and our plugin currently only rewrites the URLs. You can see how it doesn’t happen on the homepage.

However, I agree this is important for PageSpeed! Try updating the plugin and it will include a feature to automatically detect and ‘fill in’ those missing dimensions for you. This will fix that warning automatically.

Let me know if the issues continue.
