There was a bug some time ago when Trello closed many of my boards on its own. I managed to find some and recover them, but whenever I find the remaining closed boards, a message appears informing me that "Only the Administrator can open the board again." So I switch accounts to the board's administrator account, and it still gives the same message, again preventing me from bringing the board back. So I wanted to know if I can restore these closed boards again, or if I can contact system support to have them reopened?
