Why Do I See a Blank Screen?

There could be several reasons that a student sees a blank screen after they log in successfully to DreamBox. Below are four steps that can resolve this issue:

Web browsers store a large amount of information as you browse the internet. As a result, your browser may fill up with unnecessary cookies and other website data that affects its performance. This can cause the DreamBox screen to appear blank or solid blue after you log in. Clearing your browser cache will clean up specific types of stored data and most often resolves the issue. This is typically a simple process and normally takes less than five minutes. Listed below are directions to clear the cache on common web browsers. Please note that the steps may be different depending on your browser's version. Check your browser's Help menu for more information.

 Internet Explorer
Click the Tools Icon  in the top-right corner of your window and select Internet Options from the drop-down menu. The Internet Options window opens. From the General tab, look for Browsing History and click  (Delete). The Delete Browsing History window opens. Make sure the top four boxes are checked (Preserve Favorites, Temporary Internet Files, Cookies, and Download History). Click Delete, and then OK. Close all open Internet Explorer windows, open a new window in Internet Explorer, and sign in to DreamBox.

 Mozilla Firefox
Click History in the Toolbar at the top of your window. Select Clear Recent History from the drop-down list. The Clear Recent History window opens. Check the checkboxes for the following options: Browsing & Download History, Cookies, Cache, and Offline Website Data. Uncheck all other options if you would like to keep that data. Click  (Clear Now). The window disappears as Firefox clears the browser cache. Close all open Firefox windows, open a new window in Firefox, and sign in to DreamBox.

 Google Chrome
Click the Customize button  in the top-right corner of your screen and select History from the drop-down list. Your browsing history in Google Chrome opens in a new tab. Click Clear browsing data. The Clear Browsing Data window opens. Select the beginning of time from the drop-down menu at the top of the window. The top four boxes are checked by default (Browsing and Download history, Cookies, Cached images). Leave these boxes checked and make sure the bottom four are not checked (Passwords, Autofill, Hosted app data, Content licenses), then click Clear browsing data. The window disappears as Chrome clears the browser cache. Close all open Chrome windows, open a new window in Chrome, and sign in to DreamBox.

Select Safari from the menu at the top of your screen or click the Tools icon on the right side of the toolbar. Select Reset Safari from the drop-down menu. The Reset Safari window opens. All of the boxes may be checked by default. Make sure you select Empty the Cache and Remove all Cookies and, if you have the option, Remove all website data, then click Reset. Close all open Safari windows and quit Safari (⌘+Q) to close the browser completely. Open a new window in Safari and sign in to DreamBox.
Sometimes simply switching browsers will resolve the issue. We recommend using Google Chrome. Adobe Flash is embedded in Google Chrome, so it is frequently preferred for applications that use Adobe Flash, including DreamBox.
Some optional ad blocking software and extensions for various internet browsers can prevent DreamBox from opening. If you have installed any ad blocking software, please try temporarily disabling or pausing it and then reopen DreamBox.
Click the following link to visit the Flash Player Help page:
Click the Delete all sites button on the Website Storage Settings panel. A confirmation window opens. Click Confirm. Close all open browser windows, then open a new window and sign in to DreamBox.
You may see the blank screen because your security, firewall, parental control, or content-filtering software is blocking DreamBox. When you add dreambox.com and adobe.com to the "whitelist" in the security software, you are telling the software that DreamBox is safe to access. View the Help information for your security or router software for specific instruction on how to add the websites to your whitelist.
