1) Do the backup of all your files and DB.
2) If you did any changes directly in template files move these changes into the child theme.
3) Make sure that WooCommerce plugin is 3.3 and higher. If not – update plugin. Then you can use auto update option (Dashboard > Updates > check for theme updates, choose theme and press update)
Also, we can update theme for you. Just provide me admin panel and FTP access to your site.
I’m having the same issue. It was doing it before I updated everything this morning and still no images loading after updates. When I try to view the image itself it says the url is invalid. Is there a code update needed to make this work? Only thing not loading are images.
