All the cards and data are gone from my boards today. There was a message on the site that says "Hey, Trello is getting an upgrade and this board menu is moving soon. Preview the upcoming sidebar now." It doesn't mention any timing for this move.
I had a previous version open and I copied and pasted the website address to my browser and it re-loaded my page BUT when I try to make changes on the cards, I keep getting an error message that I have lost connection to Trello and most of my card headers are blank where there once was attachment pictures.
Anyone know what is going on today?
