Question Answer
The Blackboard login page displays "Page Not Found" or "URL Not Found" or "system unavailable."

Problem: When a user goes to, there is a "Page Not Found", "URL Not Found" (view sample screenshot), "This system is momentarily unavailable" or other error message.

Possible causes: This may have been caused by recent server maintenance; also, the user's computer is not set to periodically clear cache.

Solution: Clear your browser cache. No matter what browser you have, you can find the steps at how to clear cache. (NOTE: So far this problem has largely been reported by those who use the Safari browser on a Mac. We recommend using Mozilla Firefox with Blackboard even for Mac users.)

Still having login or Blackboard display problems? Try these options...
  • Clearing your browser cache.
  • Try using a different browser. We currently recommend only Mozilla Firefox for use with Blackboard. More problems have been reported with Blackboard when the MS Internet Explorer browser is used.
  • Also, AOL is not compatible with Blackboard. If you use AOL as your ISP, minimize your AOL browser window and open up Firefox to use Blackboard.
  • Try using another computer.
  • Try a computer in one of Chabot's labs (in the Library or Room 3906).
  • Test goes blank? Make sure to turn off the pop-up blocker.
I'm enrolled in a course, but there is no link to it when I login. Not all instructors use sites for their courses. For example, you may be enrolled in one class that has a site and two classes that do not.

If your instructor never mentions having a site, most likely your course does not have one.
How do I hide Blackboard course sites that I took in previous semesters?
  1. Login to Blackboard and make sure you are within the My Institution tab.
  2. Click on the pinwheel icon in the upper-right corner of the My Courses module: screenshot of My Courses pinwheel
  3. Uncheck all of the boxes to the right of each course that you want to hide.
  4. Click Submit.

Please note that the above steps only affects the display of courses on the My Institution tab. All of the Blackboard course sites that you have been enrolled in in the past two years will continue to display on the My Courses tab.

I need to check a grade from a course I took last semester. How do I get into the course Blackboard site? You will not be able to login to Blackboard to view a past course if your instructor has made the course Bb site unavailable. Most instructors make Blackboard sites unavailable to students shortly after a course has ended. For questions regarding a course you took in the past, you should contact the instructor.
How do I clear my browser's cache? Browsers will normally clear browsing history at regular intervals, but sometimes you may need to clear it manually to address an issue. Click here to view the steps for clearing cache for most browsers.
The font/text size of my browser is too small.

The most common cause of text that is too small is that somehow your browser's text gets set to a size other than medium. Assuming that you're using the Mozilla Firefox browser (which is the recommended browser for accessing Blackboard), try one or both of the following:

  1. Click View from the top menu
  2. Click Zoom In (or click on Ctrl +) until the desired text size displays.

You might also try the following;

  1. Go to the Tools menu
  2. Select Options
  3. Select the Content tab
  4. Under Fonts & Colors, choose the font size you prefer.

You may also need to refresh your browser (click the refresh button).

I copied and pasted text from Microsoft Word into Blackboard's text box editor (in an assignment or a discussion board post) and the formatting is all messed up.

The Text Box Editor, which is used in many places throughout Blackboard (Assignments, Discussion Board, Assessments), can have an issue when copy/pasting from a word processing program such as Microsoft Word. While you may only see the text that you pasted, you are also copying the fonts (and if any, hidden html code). The hidden fonts/codes are what causes the display issues.

To ensure that your content displays as you would like, your best bet is to copy/paste your text into a format-free program such as NotePad (PC) of TextEdit (Mac) and then copy it back from NotePad/TextEdit into the text box editor in Blackboard. You should then be able to edit the text using the text box editor menu. Here are the steps:

  1. Copy your text from Word (or whatever program you are using)
  2. Paste your text into a format-free program such as NotePad (PC) of TextEdit (Mac).
  3. Select all of what you just pasted into NotePad or TextEdit, and copy it back into the text box editor in Blackboard.
  4. Format the text using the text box editor menu.
I am not receiving email from my instructor or other Blackboard students in the class. Why?
The default email associated with your Blackboard account is your Zonemail. You have the option to change the email address associated with your Blackboard account, or forward email sent to your Zonemail to a personal email account. To find out how to access your Zonemail or view other available options, please go to How To Login to Blackboard and scroll down to Step 3, "Verify Your Email Address."
When I try to access the Discussion Board (or another area), I get "Internal Server Error" message.
If you encounter the Internal Server Error message, the most probable cause is that there is a temporary glitch in the system (sometimes due to heavy system-wide usage). The error message is usually only temporary and you should be able to view the area within a few seconds (you may need to click on other areas or refresh your browser).

However, if the error message continues to display, please try one or more of the following:

  • There may have been an interruption in your internet service.
    1. Logout of Blackboard.
    2. Close your browser. (You may also want to restart your computer.)
    3. Reopen your browser. A "Page Not Found" message in your browser may mean that there is no internet connection; check with your internet service provider for assistance).
    4. Login to Blackboard.

      • Clear your cache settings.
      • Do you tend to close your browser without clicking on the LOGOUT button? If so, this may be another cause of the "Internal Server Error" message. This is due to persistent cookies set by the application. Please do the following to clear the cookies and temporary files in order to login again.

        1. In Internet Explorer, go to the Tools menu and select "Internet Options."
        2. If not already selected, click the "General" tab.
        3. In the area "Temporary Internet Files," select Delete Cookies and Delete Files.
      • If you continue having trouble viewing pages or file in Blackboard within Internet Explorer, please update your Internet Explorer browser. Updates can be found at

        ? Try using another browser. See Browser and Operating System Requirements (PDF). Note that while not listed on this document, Mozilla Firefox appears to work as an option as well.
I can access the Discussion Board, but I am having problems posting my responses.
Problems and their causes vary, but check both of the items below:
  • Are you having this problem? When you submit a posting, do you receive the message: "Database Error; A database error has occurred. Unable to process the request."
    Solution: This may be caused by posting too much text in the subject field. Students who had this problem were copy/pasting their entire post in the subject field, when it should have been copy/pasted into the main text box.
  • Are you having this problem? When sending a reply, I do not get a message window. So when I try to reply, a window pops up and says "type a message."
    Solution: Various computer settings can cause problems for using various tools in Blackboard, including the text editor box in the Discussion Board (the box where you type in your response). One workaround is to turn off the text editor, which means you won't be able to do such things as change the text color, but it should prevent problems.

If any of the above does not resolve the issue, try using a different browser. View options to download Firefox here. Click here for more details about the Visual Text Box Editor and other browsers.
