 * Hi there 🙂
    I’ve just uploaded the OpenID plugin to my WordPress installation,
   but when I try to activate it I get a fatal error: Fatal error: Cannot redeclare
   class auth_openid_databaseconnection in /usr/local/lib/php/Auth/OpenID/DatabaseConnection.
   php on line 25
 * Can anybody help?

 * Sorry, to double post but I’d really like to get this fixed. Does anybody know
   how to get this to work?

 * looks like you have another copy of the OpenID library in your include path somewhere.

 * I get a similiar error, though it seems to be a PEAR issue:
 * Fatal error: Cannot redeclare class Auth_OpenID_DatabaseConnection in /home/digitax0/
   public_html/umbralechoes/PEAR/Auth/OpenID/DatabaseConnection.php on line 25
 * Any advice on tracking down the cause of this?

 * Never mind, figured it out. There was an old PEAR installation hanging around
   in my webroot — I removed that, and it seemed to install okay.

 * I have the same problem. I can’t just delete the PEAR installation, though, because
   it’s used for other things.
 * I would think that the plugin should use its own version of the Jan Rain libraries,
   if it has its own, and not pull in libraries installed elsewhere in the system.
 * Or, at least not try using both at the same time.
