Thank you for contacting our support service. I checked your website at: hidden link and I see all the images at place, it seems you have already fixed the issue or I couldn't replicate it. Can you please, let me know where I can see the missing image?
Also, I noticed for some reason your theme is calling these images using a relative url which is not something that seems default to WordPress. Please, let me know and we'll proceed with a detailed investigation, have a nice day.
Hey Marcos, I found the problem: when trying to regenerate a featured image from the second language of my website, for some reason the wp-cli regenerated the featured image from the main language. What I did is disable all WPML plugins and ran wp media regenerate command again.
