This post is also available in: 日本語 Français Español Српски Ukrainian

If there’s something odd going on in Vivaldi Calendar, there are a few things you can do in order to troubleshoot the issue.

Missing events

If you don’t see an event you’ve added:

  • Make sure displaying the calendar’s events has been enabled.
    1. In the Calendar tab, click on Calendars in the top left corner.
    2. Make sure the calendars you want to see have been enabled.
  • Browse through different Calendar views to see if the event ended up on a different date.
  • Use Search to find the event.

When you don’t see events from an online calendar in Vivaldi Calendar:

  1. Go to Settings > Calendar > Calendar Accounts.
  2. Make sure the Calendar account has been properly set up.
  3. Then check Settings > Calendar > Calendars.
  4. Select the calendar you don’t see any events for.
  5. Make sure calendar sync is active.

Re-add an online calendar

If you’ve encountered issues with an online calendar, you can try whether removing and adding it again will help. Since the events are stored on the calendar service provider’s servers, there will be no data loss.

To remove an account:

  1. Go to Settings > Calendar > Calendar Accounts.
  2. Select the account that’s having issues.
  3. Click on Delete Account below the list of accounts to remove it.

To add an account:

  1. Click on Add account below the list of accounts.
  2. Choose the account type and fill in the necessary data.
  3. Finish with clicking Add Account.

Reset local calendar

If you don’t have any important data in Calendar, you can reset it by deleting the calendar database. Your local account and calendars will be deleted and online accounts with their calendars will be removed. Follow these steps to reset the Calendar:

  1. Go to the Vivaldi menu button Vivaldi menu > Help > About or type vivaldi://about in the Address Field.
  2. Make note of the Profile Path.
  3. Exit the browser.
  4. Locate the folder in your operating system’s File Manager/Finder.
  5. In the profile folder, find a file named Calendar.
    If you wish, you can make a backup of the database by making a copy of the file first.
  6. Then delete the Calendar file.
  7. Start the browser.
  8. Set up your calendar accounts and their calendars.

Check Calendar logs

To check Vivaldi Calendar’s logs for any errors:

  1. Click on the Calendar Status button on the Status Bar.
  2. In the popup, select Logs.

Some examples of errors that can be seen in logs:

  • Error synching updates to server. Changes not saved. – Likely a network issue.
  • Server error for account ‘[account name]’. – Contact the online calendar’s service provider.
  • Parser error – Invalid calendar data received or valid data that we have not added support for yet.

You can copy the logs or save them in a file to include them when reporting issues on the Forum or in a bug report.

The logs are cleared on browser restart. To get relevant logs go through the steps that cause the issue.


Importing events from an .ics file fails

Events from an .ics file can be imported via Vivaldi menu button Vivaldi menu > File > Import from Applications or Files. When it fails, it’s possible that file includes some invalid or corrupt content.

To see if the file is valid or whether there is a problem with it you can use a validator. For example, https://icalendar.org/validator.html.
