WPOpenID doesn’t work

Hi,

I recently installed WordPress, and now I’d like to add the ability to log-in using OpenID. I was suggested WPOpenID, which seem to do what I’m looking for : http://verselogic.net/projects/wordpress/wordpress-openid-plugin/. The problem is, the plugin doesn’t work and I have no clue about what to do to make it work proprely. URL of the test blog : http://www.livresanspage.net/wp-test/

1- I first downloaded the lastest stable on SourceForge (http://sourceforge.net/project/showfiles.php?group_id=167532&package_id=190501&release_id=471609, rev. 86), then I tried the SVN trunk version (rev. 90?). The same problem occurs on both lastest stable and SVN versions.
2- I uploaded the ‘wpopenid’ folder in my /wp-content/plugins directory at my webhost.
3- I went to my admin->Plugins page and activated the plugin. There is no error message or anyting, the plugin should have been activated and should work properly, right?

Now, I log-out from my administrator account and try to go to my blog’s login page: what’s returned is a blank page. No error message or anything, just a blank page. (Very helpful, isn’t it? :-\ ) This is what appeared in Options -> OpenID tab when the plugin is activated and before I log-out from my administrator account:

Any idea on what to do to make the plugin work?

Moreover should I say that there are folders missing from the SVN version which are present in the stable release. ‘Services’ and ‘Auth’ are included in rev. 86 but does not exists in SVN trunk. I guess thoses folders contain the JanRain OpenID classes. I uploaded theses two folders from rev. 86 alongside with the rest from SVN trunk to my plugins directory. May it be the cause of the problem?

Thanks for your answers !
