Sorry to be a bother but I have been going 'round and 'round in circles on this one.
My domain is https://nelkat.net
I used Let’s Encrypt to make the site secure and it has worked well. Thank you.
Both have been declared insecure by my browser, Firefox. After reading the forums, I went to Why No Padlock, forced https on my domain and then went back to Why No Padlock. It still listed a bunch of urls within both the Moodle and the Wikitrees sites that were insecure, under the category of Mixed Content. The urls still seem to have the http prefix.
Help. What am I doing wrong???
