You wrote about this earlier, and two people, including a forum moderator, responded to your post. What’s the point in asking again? https://wordpress.org/support/topic/removing-website-name/
Note that the backlink from your screenshot comes from this topic: https://wordpress.org/support/topic/load-more-products-button-doesnt-work/
There you posted your site address publicly in two instances.
I’m not sure if you did it on purpose, but I hope you can see that the text changed and I added a reply to the old post and nobody answered.
I know where the backlink comes from, that is why I am trying to remove it.

@sterndata, thank you. I don’t want to remove the whole post, I want to edit the post so the link is removed. And this is a security concern for me.
