I just finished setting the whole site to use https.
The padlock shows up on Microsoft Edge but it doesnt on Chrome. Actually is does work on Chrome as well but only on pages and not on post.
One example–> page: https://www.fabionodariphoto.com/wrp/contattami/
works fine on both Edge and Chrome
You can check any posts. You’ll see that those who are ok for HTTPS connections won’t show the padlock on Chrome even if the content is ok.
