IE8 Script Error: 'script.parentNode' is null or not an object
I'm getting this error in swfobject.js, line 14 character 713. Everything appears to be working fine so I'm not too concerned. I just don't like seeing the error icon at the bottom of the page. I've tested this in Firefox and no errors are being reported there.
Re: IE8 Script Error: 'script.parentNode' is null or not an object
I was getting this error in all versions of IE (6, 7 and 8). It turns out that if you are using Shadowbox to play swf and flv files, it automatically embeds swfobject as well. I removed my own reference to swfobject and the error went away, and the Flash files both on the page and within Shadowbox continue to work.
So don't link swfobject on any page that uses Shadowbox.
