Sorry — your last action could not be completed

[keys76]

Hello,

Noob here;
I integrated paypal into virtuemart and when using IE8 I got the message Sorry — your last action could not be completed""  when redirecting to paypal.

When I'm using FIREFOX I won't get this message.

Anyone knows what to do? I want my customer to pay through paypal when using IE8.

Thanks a lot,

Jeroen
