captcha plugin error

[RafaelM]

I'm trying install the captcha plugin in my roundcube, but doesn't work.
I'm using version 0.2.1 on lenny (iRedMail 0.5.1)

I untar the file and copy to plugins/captcha , copy the content of captcha/config/config.inc.php to config/main.inc.php and append the line
$rcmail_config['plugins'] = array("captcha");
 before  this.
Is necessary more some config ?

Are you using RoundCube version 0.2.1 becouse plugins are only supported on RoundCube version 0.3 and greater. I'd recommend you upgrade to RoundCube 0.4.2

i had installed Rouncubemail-0.4.2 in ubuntu 9.04
all things are configured properly and its working
good.When i add captcha and put it in
roundcubemail -XXX/plugins/.Then changed the config
file from conf.inc.php.dist to conf.inc.php , added "login"
in that file under $rcmail_config['captcha_page'] = array("contactus","recpw","register");.

Then added the word "captcha" in main.inc.php file.

Now, when am checking in browser nothing is visible
even the login page isn't working.

Can any one post me the proper solution ...:confused:
