Cart is always empty in Internet Explorer 9 only

I have a ecart implementation which has been running fine for a number of years.

It appears that 'add to cart' always results in 'the cart is empty' when using IE9. The 'add to cart' button does work correctly in Firefox and Chrome

the website is www.meltons.co.uk and a URL to a shopping 'add to cart' page is as follows:

Meltons_Product_Detail.php?ID=334

Any ideas greatly appreciated !

I am not able to reproduce the problem, using IE9 items are being added to the cart as expected.

perhaps you have turned off cookies or another setting in IE 9 that is causing the cart to not work.

have you tried on another computer, or only on your personal computer?

Thanks for the prompt reply.

Yes this has been reported on another machine.

I am running 64bit Windows 7 Pro but I have checked it in the non 64bit version of IE 9 (9.0.8) and I still get the error.

I have tested your site on a number of systems running vista 32 bit and Windows 7 both 32 and 64 bit and am not able to reproduce the problem.

on all of the systems I have tested on, the add to cart button works fine in IE9

Ok - well how can i debug this error as the client sees it and I see it !

any ideas greatly appreciated

with thanks

since i am not able to reproduce the problem, it is most likely a browser setting.

it could be your Cookie settings in the browser, or security settings.

It's posible it is also a fire wall issue.

It might just be IE9.

I have a non-ecart page that will not display on my laptop in IE9 on Win 7.

It does display on another laptop in IE9 on Win 7, a workstation in IE9 on Win 7 and another workstation in IE9 on Vista.

Just not on the one laptop. Weird.

but it must be some kind of default setting if two completely unrelated machines in two different countries (France & UK) both have the same issue. The firewall would surely block all browsers and it works just fine in chrome and firefox.

Are there any other possibilities specific to IE9 ?

you may need to change your cookie setting’s in IE9!

1) Click on tools
2) Click on the Privacy tab
3) Click on the Advanced buttom
4) Accept and allow all session cookies should be checked

that was enough to do it.

Is it normal then for these to be disabled by default ?

Thank you
