multiple currency problem

[ukhong]

Hi, my site got a problem, when you visit http://www.1plus1hosting.com/domains.php , you can use the top right drop-down menu to change currencies, after that you scroll down to the bottom and click one of the green buttons "Order Now", for example, I selected DKK Danish Kroners and clicked the "Order Now", it will go to the URL https://www.1plus1hosting.com/whmcs/cart.php?a=add&domain=register&currency=11 which is based on the Danish Kroners ID 11, so the whmcs page should display Danish Kroner, however, it was displaying GBP-sterlings.

 

My site uses cookies to store currencies because I want clients to see same currencies all the time, whmcs uses php sessions, so I am passing cookie to the session and use url get function to display https://www.1plus1hosting.com/whmcs/cart.php?a=add&domain=register&currency=11 , but seems some heavy cookies still affect the sessions and disallow whmcs to show the correct currencies.

 

However, if I stay on the page https://www.1plus1hosting.com/whmcs/cart.php?a=add&domain=register&currency=11 and clean broswer cookies and refresh the same page again, it will show DKK Danish Kroners correctly.

 

Very strange problem. Please advise me how to fix it, thank you.
