I get something new called Usersnap, a box in the lower right. Maybe you need to clear your cache?
"Report a bug", "Make a suggestion" and "contact us" not working

Clearing the cache doesn't help - I'm still having the issue. Forgot to add this earlier, I'm on Linux (CentOS 7) using firefox and chrome.

Are you running anything that might be blocking scripts?

It take a couple of seconds for the process to load for both the Make a suggestion and Bug Report (they use the same code). So, if you browser is older or you machine slower, you may just have to wait a little longer.
I tested on Chrome and Firefox on Linux (Ubuntu) and it works as expected.
The same problem here. With a new update on iOS app it is showing Loading sign until the time runs out (i play bullet). Trying to report a bug doesn’t work at all… someone please help!

I cant castling. Its a big problem, how can i resolve It?
The site has changed castling to remove the ability to click the king and then the rook to castle, at least by default. If that is what you want to do you need to change the Castling Method under Settings > Board and Pieces to Legacy from Normal.
If you prefer to use click-move, you can click the king and then the destination square under the Normal setting. With drag-move you can drag to the destination square or drag the king to the rook
I've opened chess.com on my desktop. When I hover over the "? Help" at the bottom left of the screen, I get a menu with 5 option including "Report a bug" and "Make a suggestion". However, clicking on those doesn't do anything.
Additionally, if I go here, the "Contact us" button doesn't work either. So right now I'm unable to make a bug report.
