I have a blogspot website that I can sign into. Sometimes, when I try to leave a comment on the blogspot of other individuals, I get the following message: "Unable to sign in to comment. Please check your browser configurations to allow sign-in. Learn more. To leave a comment, click the button below to sign in with Google." The "button below" doesn't work. Note: this only happens with some blogspot accounts. There are other blogspot accounts that I am able to leave comments.
