Safari - problem to open some websites

I am not able to open all websites in Safari - if I enter for example Twitter.com I get the message


Safari is not able to open twitter.com because Safari can not open a secure connection to server "twitter.com" (translated from German, sorry :-))


Any ideas about? Certificate etc. seems to be ok.

I had a related issue with SSL enabled sites only. I was able to fix this by manually setting the date/time. By default it was set to use Apple's servers, but I noticed that it was off (date was 3 years ago). Correcting this by manually setting it fixed it for me.

Try disabling Java in Safari (Safari Preferences > Security > Plug-in Settings > uncheck Java from the left panel).
