 * I just installed a facebook like this plugin and a twitter tweet plugin both 
   made by the came author. When both plugins, after I activate them and go to the
   setting page, I get this warning message at the top of the page:
 * > Warning: session_start() [function.session-start]: Cannot send session cache
   > limiter – headers already sent (output started at /home1/mindstre/public_html/
   > wisdomangermanagement/wp-content/plugins/twitter-tweet-button/inc/main_class.
   > php:54) in /home1/mindstre/public_html/wisdomangermanagement/wp-content/plugins/
   > si-captcha-for-wordpress/si-captcha.php on line 763
 * Any ideas what I should do?
