# [Plugin: Jetpack by WordPress.com] Error When Previewing Single Page Edit

 * I’ve installed Jetpack and everything appears to be working fine, but when I 
   make an edit to a page, then hit “Preview Changes” I get this error message:
 * `Warning: Cannot modify header information - headers already sent by (output 
   started at /****/****/****/wp-includes/class.wp-styles.php:92) in /****/****/****/
   wp-includes/pluggable.php on line 881`
 * If I disable Jetpack, then this error goes away.
 * Any insight on how to fix this? If there is more info you need me to provide 
   to help out, let me know.
 * Thanks.
