 * After updating Jetpack to version 2.3.3, the page displayed a php error message:
   
   Fatal error: Cannot redeclare is_jetpack_support_open() (previously declared 
   in /documents/wp-content/plugins/jetpack/class.jetpack-debugger.php:5) in /documents/
   wp-content/plugins/jetpack/modules/debug.php on line 31. This looks like a problem
   in the Jetpack Debug Module.

 * How did you update? WordPress’s internal plugin updater, uploading a zip file,
   or uploading via FTP?

 * If you just delete the `wp-content/plugins/jetpack/modules/debug.php` file, you
   should be good. That was removed from the current version of the plugin, I’m 
   not sure why you’ve still got it available. :\

 * I see. I installed the update on my Mac by dragging all of the new plugins into
   the `wp-content/plugins/` folder, so it overwrote all of the other plugin files
   except `wp-content/plugins/jetpack/modules/debug.php`. Next time, I need to delete
   the old plugin folder instead of overwriting it with the update.
