Hi @Flaschenzug,
Thank you for your answer ! The issue came from the SSL certificate that expired on the 1st of october, a few hours after I experimented with that. It’s now fixed and this code is working again.
I asked myself the same questions but didn’t get much debug information, with devtools the src in image tag wasn’t filled with the image link and no error would come up. I did check if all the links in medias were in https and they were.
I don’t have much knowledge in the server side but I guess it wouldn’t let wordpress process https links when its SSL certificate is expired.
