Why would one identical url come up with two different views.  I am guessing the code has something hidden and depending on that switch when you get to that page you get one of the two views.

Comments.Text: @edwinaoliver I did not address that part of your question because it may not be chesstempo's issue at all. I have owned an IT company for 25 years now, and it would easily be something wrong with your computer, or simply the Internet being a problem at that moment. It would really need to be diagnosed by an expert to say it was there problem.

Title: Why does chess tempo fail at random; what is the biggest free database online that is reliable
ThreadText: # Why does chess tempo fail at random; what is the biggest free database online that is reliable
  
  (Asked by: username_0 on 2020-02-06)
  
  Sometimes chess tempo works. Sometimes it does not. Seems random. Is there another database that is completely reliable that is as big as chess tempo?
  
  I am looking for a DB that gives the moves with winning percentage or else percent results for WDL for each move.
