There is this function called "Check past comments against moderation list" under the "Comment Moderation" box in Options >> Discussion.
But when I clicked on it, I see lines and lines of the same error:
"Warning: strpos(): Empty delimiter. in /home/little/public_html/inkspill/wp-includes/classes.php on line 691"
I haven't touched that file at all. Is this a bug? or is this fix-able? :) Thankies!
