You're not the only one. I've tried multiple browsers (Edge, Chrome, Firefox) on multiple PCs, and I'm seeing the same thing. I'm a member of the Beta group, which is the only thing I can think of that might be central to this.
Can't see the board or the pieces

Tried leaving beta, still the same issue, so it's not that ugh

I just had to resign. Couldn't see half the pieces but I could grab the invisible squares.
Same problem here, for some reason I couldn't see the opponent's rooks or bishops.
Same issue . Cant see the chess board...
have tried all of the suggested workarounds- multiple browsers .. etc.... still have problem

I had this happen to me about 6 months ago on Chrome. For me the solution was to disable one of my extensions which was interfering with the layout of the pieces.
Also, some dark colored based themes can also cause problems with pieces not being displayed correctly.

Tried logging into Chess.com today and I can no longer see the board.
Tried hard resetting (ctrl+f5) and clearing my cache, neither seemed to work.
From what I've seeing it is impacting some Canadian members and some from Portugal and appears to be related to the CDN the site uses to serve cached images from servers closer to members.

I live in Canada and it's happening to me. I also can't see some images in other parts of the website.
Haha guess were all in the same boat. Some of the pieces werent loading for me and when i cleared my cache they all disappeared. Nothing seemed to work. When I inspect the browser a similar message appears over and over.
Failed to load resource: the server responded with a status of 404 ()
What to do?

Another Canadian who can't see the board. Tested across four browsers, cleared cache, internet files, etc, reset machine. No luck.
