I'm running wp-openid 3.3.1 on WP 2.8.4, and when I try to leave a comment on Blogger using my OpenID URL, it fails, giving me no more information than "openid error".
I'm delegating to my WP author URL from: http://zaneselvans.org
with the following:
<link rel="openid2.provider" href="http://amateurearthling.org/openid/server" />
<link rel="openid2.local_id" href="http://amateurearthling.org/author/zane/" />
<link rel="openid.server" href="http://amateurearthling.org/openid/server" />
<link rel="openid.delegate" href="http://amateurearthling.org/author/zane/" />
<meta http-equiv="X-XRDS-Location" content="http://amateurearthling.org/?xrds" />
