 * I recently upgraded to WP 2.8.1. Now while editing the comment, when I click 
   Update comment; I get this error:
 * Warning: array_merge() [function.array-merge]: Argument #1 is not an array in/
   home/xxxxx/public_html/wp-includes/comment.php on line 1097
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/xxxxx/public_html/wp-includes/comment.php:1097) in /home/xxxxx/public_html/
   wp-includes/pluggable.php on line 865
 * I checked those files on that line mentioned in the error and here is what was
   there:
 * **LINE 1097 IN COMMENT.PHP FILE:**
    `$commentarr = array_merge($comment, $commentarr);`
 * **LINE 865 in PLUGGABLE.PHP FILE**
    `header("Location: $location");`
 * Please help me. I checked the codex information but didn’t find it working.
