 * Im using WP 2.9.2 and DB Cache 0.6
 * The plugin causes an error in the backend comments section, when trying to update
   a modified comment.
 * This is the error:
 * `Warning: array_merge() [function.array-merge]: Argument #1 is not an array in/
   mysite.com/wp-includes/comment.php on line 1315 Warning: Cannot modify header
   information - headers already sent by (output started at /mysite.com/wp-includes/
   comment.php:1315) in /mysite.com/wp-includes/classes.php on line 1586`
 * Right now disabling the plugin is the only way to avoid the issue.
 * The error is also reported by other people here [http://wordpress.org/support/topic/285076?replies=5](http://wordpress.org/support/topic/285076?replies=5)
 * Any chance anyone has a fix? the author maybe?
 * Thank you!
