Blackboard Troubleshooting Clear your browser cache: In Internet Explorer, go to Tools --> Internet Options --> General Tab and choose to clear browsing history (it may also say page cache). In Firefox, go to Tools --> Options --> Security Tab --> Cache Tab and choose to clear cache. Directions will be similar for other browsers or older versions of Firefox and Internet Explorer. Once you do this you may get messages on your screen about trusting (or accepting, or running) an applet that is a third-party product used by Blackboard. If you choose to always trust content from the publisher, the message should not re-appear. If you do not trust the content then you may have problems running certain features in Blackboard. Check the Blackboard FAQ's to make sure your browser/computer is configured correctly. You can also use this browser check curtsey of Baldwin-Wallace College. Test to see if you have Java installed. If these steps do not resolve your issue please call the Blackboard Support Line at 410-871-3118.
