Password Protection form results in 404 (wp-login.php?action=postpass)

Hello All,

Here’s the problem. You’re running the latest version of WordPress, you aren’t using a customized password form (as seen in some other threads), but all of a sudden your password protected pages don’t allow access. Instead, they result in a 404 at this page:

https://example.com/wp-login.php?action=postpass

Disabling the plugins doesn’t fix the problem. Neither does switching themes to the default theme.

I’m on Site5, and all of my clients on Site5 are having the same problem.

With all the brute force attacks to the wp-login.php form, one security measure was to block any attempt at these string style parameters (ex. ?action=postpass).

This is a host issue, it’s a good thing that your host is looking after your site’s security, but in order to fix it, you’ll need to contact your host, ask them to whitelist the ?action=postpass.

That should help you with this problem. If you have this problem, you might want to post your hosting provider (and whether or not they helped you fix the problem) for the benefit of others.

Thanks, and good luck.
