I'm seeing a "Session expired" error when I try to log in. What should I do?

• Sometimes, problems with logging in can be caused by issues with cookies (small data files that your web browser downloads from websites and stores on your computer).

• One way to see if a cookie issue is preventing you from logging in is to try accessing the site in a private or "incognito" window. 
• Most browsers enable you to browse the web privately, whereby the browser won't save your browsing history, cookies or site data, or information entered in forms.
• The following articles explain how to enable incognito/private browsing:

• If you find that you can log in when browsing in private mode, then this suggests that there is a conflict with cookies or similar, and we would recommend clearing your browser's cookies and cache to enable you to log in again in future.
