Does anyone know what this error at the top of my site means:
WordPress database error: [Duplicate entry '1137771764' for key 1]
INSERT INTO wp_useronline VALUES ('1137771764', 'admin', '188.8.131.52', 'Idiot on a Stick', '%2Ftalk%2Findex.php')
and how I would fix it? I previously had the plugin installed on old WP, now he's upgraded for WP2 and so I've installed it but it gives me that error message.
Is there something I should edit in phpmyadmin? I know it's saying duplicate, and I went in and deleted the previous wp-useronline table from the database and reinstalled, but I'm still getting this.
