 * Hi,
 * This error message sometimes appears in the Statistics tab: “Server error in 
   data/compare: The response is not a valid JSON response.”
   Any solution?Thanks

 * If you install the wp debugging plugin, do you see any errors in the logs?
 * Please also check if you see errors in the browser console: right click, inspect,
   console.

 * I see some 503 errors in the log, it might be the server is rate limiting the
   api calls, your hosting company might be able to tell you that. What is your 
   hosting company? Sometimes a hosting company has some documentation on what is
   causing a 503 in their specific configuration.
