After I spent hours working on my site's new (wordpress) theme this seems to be the only trouble I've been having. No registered members or administrators (me) can post a comment (under there name).

Here is the comments.php code, if the error lies within it:

<?php // Do not delete these lines
if ('comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
 die ('Please do not load this page directly. Thanks!');
 
 
       if (!empty($post->post_password)) { // if there's a password
        if (is_user_logged_in())   if ($_COOKIE['wp-postpass_'.$cookiehash] != $post->post_password) {  // and it doesn't match the cookie
   ?>
 
 
    <p class="nocomments"><?php _e("This post is password protected. Enter the password to view comments."); ?><p>
 
    <?php
   return;
           }
       }
 
 
 /* This variable is for alternating comment background */
 $oddcomment = "graybox";
?>

  <?php /* Changes every other comment to a different class */ 
  if("graybox" == $oddcomment) {$oddcomment="";}
  else { $oddcomment="graybox"; }

i would suggest you go and look at the default theme, and see what is different with the php code, you might of deleted a line of php code and not relized.

Thanks, but I looked at the default code and couldn't find the alteration, maybe some PHP experts could find it here is my Default comment.php code:

<?php // Do not delete these lines
 if ('comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
  die ('Please do not load this page directly. Thanks!');
 if (!empty($post->post_password)) { // if there's a password
  if ($_COOKIE['wp-postpass_' . COOKIEHASH] != $post->post_password) {  // and it doesn't match the cookie
   ?>
   <p class="nocomments">This post is password protected. Enter the password to view comments.</p>
   <?php
   return;
  }
 }
 /* This variable is for alternating comment background */
 $oddcomment = 'class="alt" ';
?>
