Hello,
I've upgraded my Catalyst to the latest firmware avaliable. But after that the webpage stopped working and I see this Javascript error when trying to see "Port Status" or other pages.
Do I need to configure something for this to work?

Hello,
tough one, as this error is typically related to JavaScript and probably META tags. Make sure you have JavaScript enabled (assuming you are trying to access the switch GUI from a Windows machine)...

I'm having this problem as well on a 3560X. Georg's answer makes no sense. Javascript is obviously enabled or it wouldn't be able to throw a runtime error. Anyways, here's a greasemonkey script I wrote to fix the problem. Feel free to use it or modify it as you'd like.

unsafeWindow.mainFrame = undefined;
window.onload = function() {
for (var i = 0; i < frames.length; i++) {
if (frames[i].frameElement.name === 'mainFrame') {
unsafeWindow.mainFrame = frames[i];
}
}
}
