# Duplicate comment detected

 * I have this very disturbing problem which I am certain someone will just say “
   oh, do this” however, if I access my site from the internet and try to post duplicate
   content as in a comment response, I either receive the 500 page error or the 
   405.1 error page.
 * If, I do the same thing (using IE, FireFox or Chrome) right on the server, I 
   get the neat little “Duplicate comment detected; it looks as though you’ve already
   said that!” answer from the wp-comments.php script
 * Can anyone help me resolve this? IS there something I am supposed to add to the
   custom header field? That doesn’t seem to be the case if all is working well 
   right on the server one would think.
 * Suggestions, hints, tricks… I am open….
 * Thank you,
 * OH P.S. — If I use WP-SPAMFREE, COMMENTS CLEANSER, or WP-CAPTCHA plugins, the
   site will be lucky to post anything other than SPAM in the comments field. We
   received an email from a visitor stating they were getting the 500 page error
   while attempting to post a comment while, in the meantime, we have been battling
   off bots left and right using the wp-spamfree, and wp-si-captcha plugins…
 * I think if I can get this default code to work, along with the Human Recognition
   plugin that seems to be working dandy, we’d be all set….
 * Thanks again,
 * WNV
