Since I upgraded to WordPress 2.0, my comments haven't been taking. The comments page comes up and you can enter all your information, but then when you submit it, you get the following error:
Fatal error: Call to undefined function: wp_new_comment() in /mysite.com/wp-comments-post.php on line 51
In the wp-comments-post.php file, line 51 reads: wp_new_comment( $commentdata );
How can I fix this?
