Hercules Recaptcha

Description

Hercules Recaptcha uses the latest Google Recaptcha API to more accurately determine if users are bots or not.
If the user is not logged in it will display a Recaptcha for the user to fill out in the comment form. If the user
disables javascript and is not logged in then comments will fail to submit.

The Recaptcha is also added to the registration page for both multisite setups and single blogs. There are options for
having it show up on comments and/or the registration page, as well as options for its position on the comment form, and
which style (Google gives only two options, dark or light).

Screenshots

  • This is how the Recaptcha looks in a form on a real WordPress theme.
  • This is what users see when they press the "I'm not a robot" checkbox.
  • This is the settings page where you set the Recaptcha keys.

Installation

Add this plugin by uploading the zip using the “Add Plugin” feature built into WordPress. Otherwise manaully unzip the folder
and upload the entire directory to your blog’s plugins folder ( /wp-content/plugins/ ). Next you have to activate the plugin.

Lastly, to make it work you need to go to the Hercules Recaptcha settings page (a submenu of “Settings”) and add your
site key and and secret key. If you don’t have these yet you need to go to https://www.google.com/recaptcha/ to register your site

FAQ

Why isn’t my Recaptcha rendering?

First of all make sure you are not logged into WordPress and that you are viewing a post that has comments enabled.
If the Recaptcha isn’t displaying then you may have not set your Recaptcha keys yet. If it is displaying an error
message then you are using invalid keys (ones not associated with the domain that your blog is on) or there is some
sort of error in the keys (like an extra space in them).

Where do I get Recaptcha keys?

If you don’t have these yet you need to go to https://www.google.com/recaptcha/ to register your site
and get keys.
