I'm having problems getting this to work on my WPMU setup. After successfully installing and activating this plugin, my login page no longer works and I have users having problems signing up for new accounts due to the above mentioned errpr. The full error is as the following:
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /public_html/wp-content/themes/azul/header.php:7) in /public_html/wp-content/plugins/super-capcha/super-captcha.php on line 1153
