Hello, thank you for the support! I contacted the plugin creator and they fixed it from their side. I am now a yearly plan customer !
I have sent you an email. But fyi … i have disabled sg optimer that uses super cache, I have disabled NGINX cache in the site aswell (so i have removed any phorm of caching) and i did try with an all new single plain image, and NOTHING appears at the published page no matter what.
