So far, I have been using Movable Type’s default CAPTCHA plugin. Today I switched to reCAPTCHA. The instructions provided by John Carter did not work for me. Here is the approach I followed to enable reCAPTCHA on this blog.
1. Install Movable Type 4.1.
2. Copy contents of /extras/examples/plugins/reCaptcha into /plugins/reCaptcha directory.
3. Open /plugins/reCaptcha/reCaptcha.pl and change the following lines from
settings => new MT::PluginSettings([
['recaptcha_publickey', { Scope => 'blog' }],
['recaptcha_privatekey', { Default => Scope => 'blog' }],
]),
to
settings => new MT::PluginSettings([
['recaptcha_publickey', { Default => 'your reCAPTCHA public key', Scope => 'blog' }],
['recaptcha_privatekey', { Default => 'your reCAPTCHA private key', Scope => 'blog' }],
]),
4. Rebuild entry archives.
