When trying to log in to the Particls Firefox extension with my OpenID, I get errors like this:

"There was a "HttpError" trying to authenticate that OpenID. Please check the value and try again."

My open id is "blog.bmn.name", and I wonder wither the subdomain is causing problems with the openID library you guys are using.
I know my openID works perfectly as I use it for a number of other sites such as magnolia.
