I've installed the 2.0 version of Will Norris et al's wp-openid plugin, on WP 2.3.1, and I'm getting trouble at the end of the authentication loop. When I use openid to log in or leave a comment, it takes me to my openid host and asks for confirmation properly, but when I am returned to my wordpress site I get, not my starting page, but my login page with this error message:
WordPress database error: [Unknown column 'server_url' in 'field list']
REPLACE INTO branchjournal_openid_nonces (server_url, timestamp, salt) VALUES ('', 1194887494, 'q1AnCo')
This happens whether I am logging in from the login page, from my login widget or leaving a comment. I am a bare beginner with mysql and I'm not even sure what it's telling me is wrong. Can anyone interpret this and perhaps recommend where in my plugin files I should look to fix the problem?
