• Make sure pop-up blockers are disabled (Chrome, Firefox) - Often course materials open in a new window. If a pop-up blocker is enabled, it may cause the material to be blocked.
• Give a different web browser a try - Chrome or Firefox are recommended for accessing course materials, or e-text. Safari and Edge don't always work well; if at all.
• Clear your web browser cache (Chrome, Firefox) - Cache should be cleared regularly to increase the performance of your device, and to reset any site data.
• Canvas App - If you are using the Canvas App, and having issues, make sure your default web browser on your device is set to Chrome (iPhone/iPad, Android) or Firefox (iPhone/iPad, Android). Access the materials from Canvas directly: https://otc.instructure.com/ or through MyOTC.
• Use another device - Sometimes the device is the issue. Test out another!

If after trying ALL options listed above, course materials remain unavailable, please contact your instructor.
