Thanks for your reply. I have registered and I got
https://techews.pip.verisignlabs.com/
address.
I have installed the plugin on www.techews.com
and added https://techews.pip.verisignlabs.com/
in setting us > General .
But still when I try to enter open id as https://www.Techews.com
it shows same error on blogger blog’s comment section.
