Warning: array_merge() [function.array-merge]: Argument #2 is not an array

[lankatr]

I'm getting the error " Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home/lankatr/public_html/wp/wp-includes/post.php on line 1856"

Line 1856 :
// Merge old and new fields with new fields overwriting old ones.
$postarr = array_merge($post, $postarr);
$postarr['post_category'] = $post_cats;
if ( $clear_date ) {
$postarr['post_date'] = current_time('mysql');
$postarr['post_date_gmt'] = '';
}

if ($postarr['post_type'] == 'attachment')
return wp_insert_attachment($postarr);

return wp_insert_post($postarr);
}

$postarr = array_merge($post, $postarr);

The error message is saying that $postarr is not an array.

Since I cannot see any code that assigns $postarr a value, I cannot possibly know what the problem is.

Here what i found in post.php

Have you tried deactivating your plugins one by one to see if one of them is causing the problem?
