I am using the free version of Trello. Recently I am unable to edit or move cards. I am the admin for the workspace but can't edit or move the cards. If I log in on my old computer, I can still edit and move the cards so am not sure if it is a network setting that prevents me from editing or moving the cards. I get an error message "edit not saved". And if I move the card by dragging it, it momentarily move to the list selected, but then just moves back. If I use the "move" button. I get the error "moving card failed"
