Clear Cache in Web Browser
Posted by Jesse Chieppa on 22 Jun 2011 12:43 PM

When we perform a system update to MyPMS we are often times updating many files including web content and javascript. If your browser doesn't automatically check for new updates you may still be using a cached copy and experience problems or quirks.

If you experience any oddities after a MyPMS update please clear your browser cache and restart your browser prior to contacting support.

There are times when you may be experiencing issues with your MyPMS software that can be fixed by clearing the Cache in your website browsers.Typically, browser cache issues affect the system's ability to perform certain tasks.

These issues include:

  • Saving and completing a new booking
  • Check-in or Check-out of a Guest
  • Apply Payment
  • Cancelling a booking
  • Confirming a booking
  • Tape Chart View
  • Problems with the EZ search function
  • Problems with Daylight Savings Time dates appearing in 'white' (as opposed to 'blue') when selected on a Tape Chart.

If you are experiencing any of these issues, then try clearing the cache in your browser and logging back into MyPMS.

The steps to clear the cache vary by browser. We recommend either Internet Explorer or Mozilla Firefox and have provided the steps for clearing the cache here. Steps may differ on previous versions and on other browsers which can be easily found by searching for "clearing cache" for a specific browser in a search engine. We do recommend you have the most up to date version of Internet Explorer, both for better feature support AND important security updates that microsoft releases!
