 * I’ve received the same error.
 * The plugin generated 2 characters of unexpected output during activation. If 
   you notice “headers already sent” messages, problems with syndication feeds or
   other issues, try deactivating or removing this plugin.

 * And it is causing backup errors with Updraft.
 * Updraft says
 * > Warning: Your WordPress installation has a problem with outputting extra whitespace.
   > This can corrupt backups that you download from here. Follow this link for

 * Is there anyone watching this thread/ticket?

 * It’s not hard to fix this issue… all you need to do is open the file referenced
   and delete all the whitespace at the end.
