I switched my web from http to https by using "Better search and replace" and everything worked fine - at first sight.
All resources were deliverd via https and the Firefox showed a green lock. But when now uploading a new image I saw that it will be delivered via http.
I immediatle checked my db but in options/home and options/siteurl the entry is https. In wp-config I also use define('FORCE_SSL_ADMIN', true);. And now the curious thing: When checking the WordPress Address (URL) under "Settings/General" there is a http-entry which cannot be edited.
The db says https but the backend says http... I´m really helpless... What can I do?
