This may happen if a setting in third-party firewall software, pop-up blocking and ad-blocking software, or browser plug-ins conflicts with Google Calendar. If you believe software installed on your computer is preventing you from using Google Calendar, we suggest adding "www.google.com/calendar" as an exception to any ad-blocking, script-blocking, or pop-up blocking rules. If that doesn't help, we recommend disabling the software, clearing your browser's cache, and logging in to Google Calendar again.
Additionally, you may need to lower your browser's security and/or privacy settings. We also recommend adding "www.google.com/calendar" to your list of accepted sites. Once you've made adjustments to your browser, clear your browser's cache.
