Have you tried with Firefox?

OP’s without a question mark (?) are statements and don’t expect (deserve) a reply.

Questions do, but it’s not always the case.

;-)

I've also got this problem on a Chromebook. It has previously worked and I love the program.

Hope it's just a temporary problem.

Anyone have any ideas as to the problem or solution?

Cheers

@boromat,

I don't know anything about them but presumably you can't install Firefox on a Chromebook?

Post a Chrome bug report.

Hi aspadistra, boromat:

I'm sorry you're having problems loading CircuitLab. What would help us troubleshoot is if you could send us any output from the Chrome developer's console. You can access this console simply by hitting F12 inside Chrome.

On a side note, do you have the CircuitLab Chrome webapp installed? https://chrome.google.com/webstore/detail/circuitlab/haghanbgfkfpmepoohpigmglbfejljoj?hl=en

Best,

Yuan

Hi Yuan,

The console output is

Document was loaded from Application Cache with manifest https://www.circuitlab.com/editor/circuitlab.appcache www.circuitlab.com:1 Application Cache Checking event www.circuitlab.com:1 Application Cache NoUpdate event www.circuitlab.com:1 Uncaught SyntaxError: Variable 't' has already been declared /assets/editor/editor-compiled-1363990782.js:158

and yes I am using the web app.

Cheers Matt

Thanks Matt, I'll look into this. Yuan

Hi Matt and aspadistra,

The solution here is to disable the "Experimental Javascript" flag in Chrome. You can do this by typing "about:flags" into any chrome tab, and then clicking "Disable" under "Experimental Javascript". (You can use Ctrl-F to search for it, it should be about halfway down the page)

Relaunch Chrome and CircuitLab, and it should be fixed! Please let me know if this works for you.

Yuan

Success with the "Experimental Javascript" flag turned off. The current Chrome has Keyboard Encryption as a flag, and my view is that for this kind of application it should be disabled too.

The application (for Chrome users) when it is starting up should inform users to turn these flags off and provide a link.

This is about the 1st time an experimental flag has actually bitten ... Chrome is quite stable in spite of its problems.
