Question Error on forum

I'm getting the following page error on the forum, only on the individual pages, not one I'm on the main forum. And it is only happening on Internet Explorer not Firefox. One reason why I am really beginning to dislike IE. Any ideas what's causing it?

Now that is very strange. According to my browser, there is also an error on this forum. You'll have to look at it in Internet Explorer

That is more than likely an error due to a javascript conflict with the Default_Ex template and another extension/template.

Well whatever my problem is, you've got the same on here because I'm getting the error on a different computer

If you log in and view the forum, there is no error message on here, I wonder if that has got something to do with the logging in system? unfortunately the same isn't happening on my forum. Mind you, the error message on this forum is on a different line to mine

Thanks, OFL. I understand what you're saying: Internet Explorer shows an error icon on the status line. When you clicks the icon you get a dialog that states, rather unhelpfully, "Problems with this webpage may prevent it from displaying properly or functioning properly ..."

I use IE, too (IE 7 - WinXP), but unfortunately I cannot consistently reproduce the problem at this website.
