Lost images

My site is https://www.eccellenzeitalianfood.it.
Pages are in italian and in english, but in most of english pages images are now losts and the browser reports a broken link. Tried with Firefox and Chrome. After a check, I found alla the images correctly in the Media Library and url seems ok.

Page with missing images:

https://www.eccellenzeitalianfood.it/2010/09/condimento-aromatizzato-biologico-al-tartufo-bianco-campus-u-montecastrilli-tr/?lang=en

My solution is to re-insert images but I want to debug this situation.

Thanks.
