Clearing Browser Cache

To improve performance for frequently visited websites, internet browsers (Chrome, Firefox, Safari, Edge and others) maintain temporary storage of static files and pictures that make up a web page. When website administrators make changes to a site, a page may temporarily display in an unusual or unintended manner due to a combination of new and old files put in use by the browser. If you experience a website that is displaying a garbled page you may be able to correct this in your own computer by clearing your browser cache.

Windows and Mac computers have a simple combination of keys to “force refresh” a page and it is recommended that you first attempt this type of reload before clearing further saved data. These are the commands used for this force refresh:

Windows: Ctrl and F5
Mac: CMD and R

If issues still persist after the force refresh, you may need to clear your browser cache to force your computer to download the updated version of Blackboard and other websites that your browser is temporarily caching. Below are instructions for the recommended browsers for using Blackboard:


  1. Paste this link into your browser: chrome://settings/clearBrowserData
  2. Select All Time from the time range and check the box next to Cached Images and Files then Clear Data


  1. Go to Options > Privacy & Security
  2. In History, select Clear History
  3. Select Everything from the time range, check the box next to Cache and select Clear Now


  1. In the History menu, click Clear History
  2. In the pop-up window, select the longest time range then Clear History


  1. In Settings, under Clear Browsing Data select Choose What to Clear
  2. Check the box next to Cached Data and Files and choose Clear

If you continue to experience problems after clearing your browser cache, please contact Blackboard Support by emailing or by phone at 531-622-2834.
