Geeklog reCAPTCHA plugin

# Install/Uninstall/Upgrade instruction for the Geeklog reCAPTCHA plugin

## What is reCAPTCHA?

ReCAPTCHA® is a free anti-bot service providing powerful CAPTCHA. This plugin makes it easy to use reCAPTCHA with Geeklog.

As of reCAPTCHA v1.2.1 a reCaptcha API was added which plugins must now use to enable support. Plugin Integration for reCAPTCHA is now controlled in the Plugins own Configuration now (and not the reCAPTCHA configuration).

## System Requirements

- Since v1.2.1, PHP-5.6.4 or later is required.
- Since v1.1.6, Geeklog 1.8.0 or newer is required.
- Since v1.2.0, Geeklog 2.2.0 or newer is required.
- Since v1.2.1, Geeklog 2.2.1 or newer is required.

## INSTALL

In the following descriptions

- <geeklog_dir> is the directory where the system config.php file resides
- <admin> is the directory where the administration files reside (usually, under <public_html>)

1. Uncompress the recaptcha plugin archive while in the <geeklog_dir>/plugins directory. The archive will create a directory called recaptcha in the plugins directory.
2. Create the admin directory. Under your <admin>/plugins/ directory, create a directory called recaptcha.
3. Change to your <geeklog_dir>/plugins/recaptcha/ directory. Copy the files in the admin directory to the <admin>/plugins/recaptcha/ directory your created in step 2.
4. Log in to your Geeklog as a root user, go to the plugin editor and click on reCAPTCHA. If the install failed, examine Geeklog system errorlog for possible problems.
5. Important: Set up API keys. Go to the Configuration and enter reCAPTCHA API Site Key and Secret Key that you can get at https://www.google.com/recaptcha/admin/create. It is not until you set the API keys that you can use reCAPTCHA service.

## UNINSTALL

1. Log in to your Geeklog web site as a root user, go to the plugin editor and click on reCAPTCHA. If the unstall failed, examine Geeklog system errorlog for possible problems.
2. Delete the two plugin directories created in the install process: <geeklog-dir>/plugins/recaptcha/ and <admin>/plugins/recaptcha/.

## UPGRADE

1. Log in to your Geeklog web site as a root user, go to the plugin editor and disable the reCAPTCHA plugin.
2. Uncompress the recaptcha plugin archive and upload the resulting files as you did when you installed the plugin.
3. Go to the plugin editor and Enable the reCAPTCHA plugin. Then, upgrade the plugin.
