I’ve given up trying to make the WP-OpenID plugin work with my theme. It seems it just doesn’t want to. Watever I do, it either tries to always authenticate on the url (even if it isn’t a provider) or never. I can’t get to it actually check the site.
Also, even if I do use a url that provides openid auth, the comment is rejected as spam (probably by bcspamblock) and I can’t be bollocksed to troubleshoot that.
So for now, unfortunately, I’m disabling OpenID functionality on this site. Let’s hope this can be fixed in the future.
