thanks for the different tickets; it's easier to keep the overview. But on your front support page, it is recommended to just open one ticket.
So we keep this one here for 5. Page certificate hidden link
Okay I noticed that the error is on our WP staging site, the editor of the page looks different from the view of the page.
But there is one issue with WPML Media
I added all testimonials to the WPML media library. I don't understand why the second one in the carousel has a different name than the others.
But unfortunately the image stays in English on the German page.
From what I can see, the issue is likely related to image sizes. In the default language, a scaled/cropped version of the image is being used, while in the secondary language the full image is used. Because of this mismatch, WPML does not recognize them as the same image, so the translated version is not shown.
This can happen if images were optimized or resized after upload.
I suggest installing a plugin like “Regenerate Thumbnails” and running it so all image sizes are properly generated across languages. After that, the correct (translated) image should appear on the frontend.
From my check, the image itself is translated correctly, it’s just not loading the correct version.
