Why do I get the "Page expired. Please click on OK to realod the page." message?

There can be 3 reasons why you get the "Page Expired" message:
  • You have left Bookmark Ninja open in a browser window for a long time (e.g. the Dashboard for 12 hours) without any interaction and the session has timed out.
  • A new build was rolled out to the server while you had Bookmark Ninja open in your browser window. The reload is necessary because of the new build.
  • You opened Bookmark Ninja and keep it open in several browser tabs parallel and the session reached  the maximum number of views it can store. In these cases the pages will reload automatically. If the auto-reload is not possible for any reason you will get the "Page Expired" message to reload the page manually.
