Why did my jira board got deleted?

[Fronetic GmbH]

Yesterday I changed some permissions using user groups. This is the log:

Gestern JIRA group management User removed from group jira-software-usersJIRA Internal Directory
Gestern JIRA group management User removed from group jira-administratorsJIRA Internal Directory

Gestern JIRA group management User added to group confluence-usersJIRA Internal Directory
Gestern JIRA group management User added to group confluence-administratorsJIRA Internal Directory
Gestern JIRA group management User added to group confluence-usersJIRA Internal Directory
Gestern JIRA group management User added to group confluence-administratorsJIRA Internal Directory
Gestern JIRA group management Group created confluence-administratorsJIRA Internal Directory
Gestern JIRA group management Group deleted froneticJIRA Internal Directory

After doing this my jira board got deleted. Nothing metioned about that in the logs.
Where is my board and how can I restore it?

Was the board only visible to the group that was deleted?

Hi!

Not only, also to jira administrators. But im a jira administrator and I can no longer see this project.

[Jack Brickey]

You can’t see the project or you can’t see the board?

if you still can access the project and the board does not exist in the “view all boards” then simply recreate the board.

Cant see the board. "recreate" includes all the tickets which were on the board?

Boards are a view of issues, not a container.  Deleting a board does not touch the issues, they're still there.  So if you re-create a board, it will select the issues it selected before.
