I have a friend with a wordpress.com site. Why are folks asked to sign in when trying to leave a comment on her site? A box pops up that says "You're trying to publish a comment as [email redacted]...You need to log in to that account before you can proceed. and the other side of the box says "You are being asked to login because [email redacted] is used by an account you are not logged into now. " Seems like she might be not getting comments because of this.
The weird thing is is that sometimes I will be able to comment and sometimes not. I comment on other wp.com sites with no problem. I though at first that it might be a gravatar thing but it also doesn't let a regular (non-gravatar) email address go though either.
Can someone please explain what the settings should be so that this does not happen.
Her site is : https://lovewildlifephotography.wordpress.com
Thanks for any help.
