Hi, I'm new here and I played one game against the computer, but now after several days of trying I can no longer play against the computer for some reason. I click on start and nothing happens.
It appears to be a problem of the security settings in the browser. To disable them go to the settings/options in the security tab of your selected browser. There you should see a tick box that says "Block dangerous content" or something similar, remove the tick and you are ready to play. Only remember to renable them when finished.
Something changed recently. I was playing against the computer every morning until being away for week or so. At first I thought it was Firefox, but Microsoft Edge in Windows Ten Pro does the same thing. It will not allow dismissal of the two boxes that pop up on screen. No amount of clicking anywhere seems to work. The menu allows every other feature of Chess.com to work except "Play Against The Computer" I sent a bug report a couple days ago and haven't heard back. Very frustrating! Maybe if everyone who can't use it reports it, we can get it fixed soon.
Nikos, that's a temporary fix that hopefully will not be needed long. I'll have to try it. What browser are you using?
Internet Explorer 11.103 works without any settings changes. I unchecked install newer versions automatically on the "About" page until this gets figured out. Should not have to use an outdated browser.
Hi. I am new here. I can't play against the computer. When I click on "vs. computer". It will try to take me to another window to play, but, then I receive a message at the bottom saying, "a problem with this webpage has caused Internet Explorer to close and reopen the tab". It then shows that it cannot send me back to chess.com and the window tab at the top says, "Website restore error". Can you help?
