YMAPConfig is undefined on IE8

April 5th, 2009 by Andrew Chen

IE8 came out not long ago and I just installed it and try it out

knowing that I would care much about its new features. But I was disappointed the first time I used it after installation. I went to Google Map it didn’t work and I went to Yahoo Map it didn’t work either. I mean the entire map was not able to display on IE8. When I went to Yahoo map I got a java script error saying, “YMapconfig is undefined” or something like that. I was wondering what went wrong with Microsoft. So what I have Firebox I don’t have to use Microsoft.

I didn’t find the problem until I went to Youtube. Youtube said my IE8 security setting prevented the video from being played. That is true. Seems to me the the default security level IE8 choose for internet zone is medium high level. After I set the security level to medium level everything works just fine. So how to do that? Go to Tools menu, go to internet options, go to security tab, select internet zone, drag the level bar to medium an apply. That is it!
