Support » Fixing WordPress » 404 error on comments

  • Hi all,
    I’m running a blog at and lately more and more commenters tell me that they cannot leave comments but instead are re-directed to 404 error. the issue here is that this only happens for ‘some’ people and not others(!) it doesn’t happen to me on any computer – which also makes it tricky for me to see if I fixed the issue.

    I’ve already looked this up plenty and can rule out permalink issues or browser-related issues. wp-comments…php files exist on the server and so does .htaccess. I can also rule out plugins as I haven’t installed anything in a long time.

    Is there a chance that this issue might be host-related (I am using namecheap) or else exist at the user’s end? can anyone else think of a fix that might work? many thanks!

  • Addendum: I might have narrowed something down here.

    So, my friend who gets the 404 error gave me his login he uses to comment with (name + email). I try it out and behold, I TOO get the error. on the exact same browser window, I can post fine with my data but not with his (he uses a valid hotmail account).’s what I do next: I change only his email. it works. now I change the email back to before (when it didn’t work) and now it DOES work. next thing I try my own data again, and those don’t work any longer. it’s like…completely erratic?

    this makes no sense to me. /lost
    what I can confirm is that I get the error myself unless I log in via WP admin panel first.

    anyone encountered this issue before?

    It might have something to do with validation-129 Errors, 51 warning(s),

    and javascript errors.

    Try cleaning it up first.

    I’m not sure I know how to, sorry.

    what I’ve done tonight is the following:
    – update wp
    – deactivate all plugins
    – change to default wp theme
    – restore permalinks default

    there are still errors and I still get a 404 error when attempting to leave certain longer comments. i realize it might have to do with duplicate comments and I keep thinking the issue is on WP’s side or my host. 🙁

    I can basically leave some comments just fine but not others. it’s nuts.

    It works with IE but not with Chrome or FF.

    Can we see the site with all plugins deactivated and
    the default wp theme?


    plugins folder is fully deactivated on the server. permalinks are default and theme is twenty twelve. does this help?
    I just tried to comment and I get an error despite all this:
    You don’t have permission to access /wp-comments-post.php on this server.
    Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.——

    also, I cannot seem to export my blog via wp export function (may be a connected issue?). I only just realized this – I get the following error (from all browsers):

    —-Firefox can’t find the file at—

    OR with IE

    Try checking your site’s error logs for a more specific error message. Your hosts should be able to help you in accessing your site’s error logs.

    Yeah nevermind. I am going to get professional help.
