 * Starting yesterday I’m getting 2 new warnings when I do a back up:
 * [WARNING] (503) Your app is making too many requests and is being rate limited.
   503s can trigger on a per-app or per-user basis. Wait for 1 seconds.
 * and secondly;
 * [ERROR] DropBox API: (52) Empty reply from server
 * It still shows the backup gets transferred at the bottom, but wondering if there’s
   something I need to fix ? I haven’t noticed any 503 errors on my site.
 * Thanks!
