Hi and Thank you for your reply. This orange exclamation mark is only occuring, when I select a picture from a page I edit. All other stuff is fine (articles). Even if I choose a picture from “set post image” of an article. Thats kinda strange and could not find out how to fix it. I have no problem with my wordpress in general. I guess its the fact that the mediathek is uploading the files in http and not https
But thanky anyway 🙂
