java computer doesn't work

Up to yesterday I was able, in chess mentor, to play the position against the computer, clicking allow the blocked application and accepting the risk. I go to sleep last night at 22:08, nobody entered my house or did anything, and this morning BOOM, I cannot use anymore the engine to play chess positions against, because during the night, also if nobody used my computer, magically happened that the application has been blocked by security settings (that I didn't change before to go to sleep).

  Here the details, and the pic, did it happened to anyone else?

Hmm, I'm investigating now. It seems there are a few people with this issue. I'll update you on my findings :)

Longo2012, what browser are you using when this happens? I ask because it seems to be working fine on Google Chrome.

I'm using Mozilla Firefox, but I tried also Explorer, and gave me the same problem. But again, yesterday, before I went to sleep, it was working.

Firefox for windows is still compiled as 32-bit application, so you need a 32-bit java runtime being installed. And of course you may relax any security restrictions your firewall may have set.

Again, I know it is difficult to read. Yesterday, the same mozilla firefox 32 bit, before I went to sleep, was working perfectly on chess.com

So the logic is not 32bit or 64bit or 128 and so on, but it is something which happened between the moment I went to sleep, and this morning.

Maybe it would help to know if chess.com made some changes, or if Firefox/Microsoft Explorer (Which I tried when Firefox wasn't working, giving me the same result) at Internet level made some changes to stop every app running java.

I am also blocked from play v. computer. Java security warnings etc. Any updates would be appreciated. 

Must have been the Windows update last night.

Java updated and no longer allows you to check the box acknowledging the security risk and continue anyway.

This is a good thing.

Chess.com needs to sign their java app because they're putting their users at risk. Java has allowed users to acknowledge the security risk while people update their apps to be signed, but they can't do that forever, because obviously people will happily run vulnerable software forever. Chess.com needs to sign their app.

So if I understand correctly, it is chess.com which must make their app safe for the users, signing it through Java. That would explain why this morning wasn't working anymore.

To the staff:  any idea when this issue will be resolved?  I use google chrome now and it won't work.  This is frustrating, as I am sure a lot of people like to play against the computer.  Thanks.

This isn't relevant to the OP who appears to be using a PC, but for mac users, the latest Java update requires a 64 bit browser.Chrome is 32 bit, but Safari is 64. My understanding (correct me if I am wrong) is that recent mac os updates blocked the older java plug-ins from functioning because they aren't secure. Maybe the same thing is true of windows?

I'm sure that the programmers at chess.com are trying to solve the problem. However, maybe if you, or other members who paid the diamond membership, open a ticket, then we can be sure they will do their best to solve it sooner.

I am also having this problem.

Maybe you guys want to take a look at http://www.java.com/en/download/help/appsecuritydialogs.xml.

Probably you had an (automatic) Java update and now Java is preventing the unsigned chess.com applet from running. Quoted from the link above:

"However if you understand the risk and still want to run the application, you can add the URL of this application to Exception Site List, which is located under the Security tab of the Java Control Panel.
How to manage and configure Exception Site List?
On successfully adding this application URL to this list will allow it to run after presenting some security warnings."

I can't say for sure with Windows, but I don't think the issue is with chess.com. I think the problem is that your OS isn't allowing you to use the older non-secure versions of Java (version 6?), and if you want to use java for anything anywhere on the web, you need to update it to the latest version (which could require you changing browsers).

For example, I normally use Chrome, but if I have to use java for some reason, I'll open Safari since that 64-bit browser will accommodate Java 7.

Try testing java somewhere else or go to the Oracle Test Java page. I suspect you will find the problem isn't restricted to chess.com

This behavior (preventing unsigned applets from running by default) has been deliberately introduced with Java 7 Update 51, so updating to the newest version is not likely to help.

Chess.com could of course improve the user experience by signing the applet.

Maybe it costs money to sign the applet. Maybe java ask like a 5% or few cents for everytime the thing is used, and that would ruin chess.com?

Don't blame chess.com that they did not sign it, it was unnecessary so far. To sign it, they need a certificate, which can be self signed (costs nothing, but at least you get additional warnings from the Java runtime, if it works at all) or signed by a trusted authority (not free, but quite cheap).
