If you encounter the above error when using a Chromebook to take a LockDown Browser-required exam, please do the following:

Step 1: Ensure the extension is both installed and enabled:

a) Enter the following in the URL address bar in Chrome: Chrome://extensions/
b) Locate the LockDown Browser Chrome Extension. If you don't see it listed, it's not installed. You can use your institution's LockDown Browser download URL to install the extension. This URL is typically found on the quiz summary page.
c) Ensure the LockDown Browser for Chromebook extension is enabled (toggled "on" with the slider all the way to the right.)

Step 2: Clear all cache and cookies and site data within the Chrome Web browser:

a) Enter the following in the URL address bar in Chrome: Chrome://settings/clearBrowserData
b) Select "All time" for Time Range
c) Select "Cookies and other site data," then click the "clear data" button.
d) Enter the following in the URL address bar in Chrome: chrome://settings/siteData  
e) Click the "Remove All" button to delete all leftover cookies and site data. A pop-up window may appear, asking you to confirm. Click the "clear all" button in this pop-up.
d) Restart your Chromebook, log into Moodle and attempt your exam again.

If the problem persists with your exam, it's likely that the above steps did not sufficiently clear out the cache/cookies, and so we recommend you install and use a separate "cookie cleaner" extension. Our testing shows these extensions typically work better at the task of cleaning out cookies and cache. One example would be CyberGhost Cookie Cleaner:

Once installed, you'd want to open the CyberGhost extension, choose the "browser" tab, and select all three options, as shown below. Then click the "clear browser" button. Once done, you'll need to log back in to your Learning Management System and attempt your exam again.
