I found a link that is something like “hxxps://i2.wp.com/test.o6asan.com/img/xxxxx.jpg?ssl=1” on the WordPress access log. I went to the page for checking the link. Yes, it was there. But, I couldn’t find such a link from the editor on my WordPress Dashboard. I could see the link “hxxps://test.o6asan.com/lmg/xxxxx.jpg”, though.
