Chrome has a 'cache'. It saves copies of web pages you visited. If you later go back to that same web page, Chrome pulls most of that page from its cache; this is faster than waiting for the website webserver to send the page to you.


Sometimes that cache overloads Chrome. It has too many copies of too many old pages and it has trouble keeping track of them. Then your web application might be flakey: it might not change pages when you click for the next screen; it might only show part of the page.


If that happens, you need to clear those old pages out of Chrome's cache. Here is how to do that:


  1. Open Chrome. Have only one tab open.
  2. Press these keys together: Ctrl Shift Del. This opens Chrome's cache settings.
  3. Make sure all three items on the Clear browsing data box are checked.
  4. Change the Time range to All time. We have not had good luck with the shorter, recent options.
  5. Click the Clear data button on the lower right.
  6. Once Chrome finishes clearing the cache, close it and then open a fresh instance.
