AOL Calendar lets you conveniently keep track of everything in your life and integrate it AOL Mail. While we strive to keep everything going without issues, sometimes problems can happen. If you're having troubles accessing events, viewing your calendars, or any other problems, try the following troubleshooting steps.
Restart your computer
Sometimes the old "turn it off and on again" actually works! Restarting your web browser or computer will clear our the internal cache or memory and will often fix most random computer problems.
Reset your web settings
Sometimes installing multiple browsers can result in your web settings getting changed. You can reset your general web settings without changing the settings of all web browsers on your computer.
Clear your browser's cache
Cookies are little bits of info stored in your browser to allow websites to load quicker. While this usually makes it faster to access sites, this stored info can cause some sites to have loading errors. Clearing your browser's cache will reset it back to its previous state. Doing this will wipe out all the little unwanted bits of info that have been stored in your browser, and make it overall run better.
Change the color to default blue
Sometimes, a change in the calendar's color can cause the issue with its functionality. Changing it back to the default color can reset everything and get it working again.
1. Sign in to AOL Mail.
2. Click Calendar.
3. Click the Select Calendar icon

4. Click Edit next to the calendar you want to edit.
5. Click the Drop-down icon next to the calendar's current color.

Make sure the calendar wasn't edited
If your AOL Calendar is shared, other people can edit information on the calendar. To verify the calendar was not edited, you'll need to contact everyone who can access your calendar to enquire whether they made any changes to the calendar.
Make sure your calendar is set to be displayed
Since you're able to have multiple personalized calendars in AOL, you can choose which one you want displayed at any time. If your main calendar isn't selected, your calendar will appear to be blank or have missing info.
1. Sign in to AOL Mail.
2. Click Calendar.
3. Click the Select Calendar icon .
4. If the calendar is greyed out, click the calendar to enable it.
Make sure JavaScript is enabled and updated
If nothing else works, make sure you have Java scripting enabled and updated. If Java scripting is disabled, many websites, including AOL Mail and Calendar, won't work properly.
