I was moving one Card Ticket to the Backlog, but I have accidentally click the Hide Card Button, how will i be able to view it or unhide it to the Board or Backlog?
The Hide Card button appears when you add an issue to the backlog, and this issue doesn't match the saved search that is used for the backlog. So the card is already removed from the board but not added to the backlog because of the saved search. It means that you need to find the corresponding issue on the Issues page and add it to the board once again (or edit it or the backlog saved search so the issue matches the saved search).
