General Troubleshooting Tips

In general, we recommend the following:

1. Keep your browser up to date. Not only could this prevent a web-page from being viewed properly, it is a good cybersecurity task.

2. Clear your browser history. Bad cookies can prevent a web-page from loading properly. This is also good for general browser maintenance, particularly if you notice your browser is slow loading certain pages.

3. Disable and/or remove plugins. If you have installed plugins or extensions to your browser, try turning them off or removing them one by one to see which one may be messing with Copyleaks. Also, if you have an ad-blocker, ensure that you have set https://d2l.canisius.edu domain as a “safe” URL (steps on how to do that may vary depending on the ad-blocker. See their specific website for more details).

4. Try accessing Copyleaks from a second browser. While they recommend Google Chrome, sometimes Google may update Chrome which “breaks” the Copyleaks webpage. Copyleaks is compatible with a wide variety of browsers.

5. If none of the above works, try accessing Copyleaks from a different computer. We recommend the computers in the Library, as they are typically up-to-date and have no extensions on any of the browsers. This really is just a troubleshooting step-- it does not necessarily mean that anything is wrong with your computer. Simply that something on your computer is interfering with Copyleaks for some reason.

6. See below for Copyleaks’s recommendation.
