Answers.Text: Again, without seeing it, I cannot comment on that. There may be some other reason like your browser and/or the cookies (try a different browser for a while and test), your Internet connection temporarily being a problem, or even the route to their server. Look at the source code. It is the same exact page.

Title: Whats the difference between these chess tempo databases

  (Asked by: username_0 on 2020-02-09)
  
  Chesstempo seems to have two pages for database display.
  
  This one works at random: <https://chesstempo.com/game-database.html>
  
  Sometimes it shows the moves in sequence of most usage and then the probability of WDL. Other times it shows nothing.
  
  This one seems to work all the time: <https://old.chesstempo.com/game-database.html>
  
  **What is the difference between the two databases?**
  
  Does that 'old.' refer to the database or to old code to display the database?
  
  It seems to me that the 'old' UI works right and the new one is full of bugs. Or is there some other features I am missing. Still need an answer to [the related question here](https://chess.stackexchange.com/q/28342/20569).

  They are currently exactly the same.
  
  Typically, when a website does the old.sitename.com, it is to allow people to temporarily use the old format of a recently-updated website. Over time, they phase out the old one in most cases. The underlying data, such as a database, does not change at all during this transition, just the aesthetics and layout of the webpage.
  
  In this case, it looks like they already phased out the old version, but simply kept the URL for convenience: They are currently exactly the same. To prove this, I did the following:
