 * Every time I activate this plugin in crashes the entire site. Here is the site
   URL – adellejuliet.com
 * Here is the error message:
    Fatal error: Cannot redeclare class Sharing_Advanded_Source
   in /home/content/289540928/html.wp-content/plugins/jetpace/modules/sharedaddy/
   sharing-sources.php on line 181
 * I think I see the problem, but would like confirmation and input from support.
 * Thanks

 * Do you have the Sharedaddy plugin installed? [http://wordpress.org/extend/plugins/sharedaddy/](http://wordpress.org/extend/plugins/sharedaddy/)
 * If so, deactivate and uninstall that before activating Jetpack.

 * I’m having a similar issue. I have a clean WP 3.5 install and NO plugins loaded.
   I loaded the Karma theme from ThemeForest. Everything was working fine…UNTIL…
   I attempted to link to WP.com. Once I did that, my site went off line. I cannot
   get to any page front or back end. Just white blank pages. Any ideas on how I
   can undo this?

 * [@djmorrow](https://wordpress.org/support/users/djmorrow/) Could you start a 
   new thread, since the issue seems to be different?
 * Could you try to switch to a different theme, like Twenty Twelve, to see if that
   helps, and if the problem is linked to your theme?
 * Could you also check your server error logs? That could helps us to find out 
   more about the errors on your site.
 * If you do not know how to check your server error logs, your hosting provider
   should be able to to help.
