One page checkout ie8 KKGWTServiceIf.isLoggedIn exception

[veducko]

Hi,

I am getting a strange exception on one page checkout when accessing with IE8. FF is fine and even some IE8 are fine (but most are not). I haven't modified one page checkout functionality. Any ideas?

Thanks!

I can't reproduce this.  I've just placed an order on our live demo site at http://www.konakart.com/konakart/ using IE8 and I don't see any exception.

How do you reproduce this?

BTW. which version of KonaKart are you using?

This is working fine in 90% of cases - development server is fine, test server is fine, but it occurs on production server.
I have an IE8 (256-bit) and it works fine on it, but my college has 128 bit version and he always gets this error.

We are using konakart 5.0.

Also to mention, the conacart application is on our production server and  is iframed in our customer's web pages - see below:

Could this cause an issue?

Thanks!
