Sometimes your application has been working just fine, then suddenly it is not working the same anymore. Or not working at all. This might be due to past usage information stored in your browser's cache.
Browser cache is a way browsers download website images, data, and documents for faster viewing in the future. By keeping a local copy of some website information, your browser will be able to load at least some information from each page you have visited without downloading that information again from the server. This can decrease the time it takes to load a webpage.
The downside is that the information on a website may have changed since your browser saved it the last time. This can cause unexpected results when you are running the application the next time. It could be time to clear your cache.
Please follow the link below for instructions on how to clear your browser's cache. NOTE: this process is recommended for clearing your cache only. Do not choose to clear cookies, browsing history, saved passwords, or other data. Instead, wherever possible, choose options to clear your cache only.
If you are not using one of these browsers to access your course, we recommend switching to one of these on a laptop or desktop for best results.
