When someone wants to leave a comment and forgets to fill out a required field it will be redirected to a ugly plain WordPress page that doesn't fit the design.
I have looked into the specific file (wp-comments-post.php) but do not understand enough of it to alter all of this...
Is there a easy way to change the looks of error pages?
It seems to miss all header and footer things and so, but when I add these all hell breaks loose...
