Hi, I started writing out this question but solved it for myself. I'll anyway post this because I don't know why this error was happening.
This started happening yesterday, before that Trello used to work fine. I see an empty board if I try to 1) open a board or 2) open a card directly by its link as in the screenshot below:
I've tried 1) logging in and out of trello, 2) restarting my browser
Neither of these work. It works fine if I open it in another browser or open it in private mode.
If I opened my console, I could see an error which was like "DOM Quota has been exceeded" and other which went "localstorage isn't available". Unfortunately, I didn't take a screenshot before I fixed it.
The only difference between opening in a private window and my regular browser was the cookies and localstorage. So I decided to clear both and then logged in. This time it worked.
I suspect that the error might have been due to [not catching the exception which occurs after localstorage quota has been exceeded](https://stackoverflow.com/a/22412342/1412255). The dev team might be able to investigate further.
