What is happening with chess.com?

A few hours ago while I was on this site suddenly a message occcured saying "No site configured at this address " .Now I can open the site and login, but not directly from www.chess.com. I use other links such as www.chess.com/home to find the site. Do you have any idea what is happening?

we did notice some problems with global internet providers a few hours ago. maybe that is persisting for you? we aren't seeing any other reports or issues...

Yes, it is persisting. The good thing is that I can login through the other URLs.

But when I click "home" to see e.g. the opening of the day it says "No site configured at this address " !! It is funny.

Can you try clearing your browser cache?  Or try opening the site from another browser?

I don't know how to clear the cache in firefox. You are right about changing browser, ie opens the home page in 2 seconds.

Thank you.

My interface is different, but I found the option to clear history.Now it works ok.Thank you all.

Awesome!
