Please always use a recommended browser for Moodle. Browsers are free to download; here are links to their official sites:
Apple Safari - For Mac users
Please do not use Internet Explorer/MS Edge as there are many areas that will not function or display properly.
If you are using a recommended browser but still have difficulty with a Moodle course function, please update your browser and retry the function. If it still does not work correctly, contact the Help Desk at email@example.com.
