Images don't appear in single posts

Hello !
Since the last update of the Envato Theme ( Soledad ThemeForest) the post images don’t appear either on a website/ iPhone / iPad
they do appear when I create my post on Wordpress and previsualize it . What’s going on ?

thanks

Assuming that WP is up to date as well as the theme then your best option is to ask the author (make sure your cache is also cleared) https://help.market.envato.com/hc/en-us/articles/203039054-How-to-contact-an-author
