Calendar View is completely blank on one specific Trello board

Hi, we are experiencing an issue with the Calendar View on one specific Trello board.

The Calendar View is completely blank, even though there are many cards with due dates in September 2026. All cards and their due dates are still visible normally in Board View.

We have noticed the following:

• Cards with valid due dates are visible in Board View but do not appear in Calendar View.
• Clicking on an empty date in Calendar View does nothing. Normally, clicking on a date allows us to create a new card.
• The Calendar Power-Up is enabled, but clicking its Settings button does not respond.
• We tested the board in Chrome Incognito mode, but the issue remains.
• The Workspace Admin experiences the same problem.
• Calendar View works normally on our other Trello boards.
• The cards themselves are still accessible and editable in Board View.

Therefore, the issue appears to be specific to the Calendar functionality of this particular board rather than the browser or individual user account.

Could you please advise how we can restore the Calendar View without affecting or deleting any of the existing cards?

Thank you.
