# wp-cron error

 * I recently disabled the wp-cron in WP and added it as a cron job in order to 
   make it run more regularly and reliably. That being said, when I added the cron
   job, my installation emails me the output of that job. I never noticed this issue
   before but now I get:
 * > WordPress database error Duplicate column name ‘blog_id’ for query ALTER TABLE
   > wp_page_expiry_info ADD blog_id BIGINT NOT NULL made by require_once(‘wp-load.
   > php’), require_once(‘wp-config.php’), require_once(‘wp-settings.php’), include_once(‘/
   > plugins/page-expiration-robot/expirer.php’)
 * I removed the blog_id in the DB as I was hoping because it said require_once 
   it would just execute once when it doesn’t exist. Well. The blog_id was created
   successfully, but since that, I am getting the same error again. I looked in 
   the expirer.php for that query and disabled it, but then I get another error
 * > WordPress database error Query was empty for query made by require_once(‘wp-
   > load.php’), require_once(‘wp-config.php’), require_once(‘wp-settings.php’),
   > include_once(‘/plugins/page-expiration-robot/expirer.php’)
 * Any help is welcome.
