change status email porblem

[wolf]

When changing the status of an order, the customers gets the mail, where he can click on the url to see his order. But there is missing the domain name in front.

What i get is:

 

/shop/account_history_info.php?order_id=4

 

instead of:

 

http://www.domainname.com/shop/account_his....php?order_id=4

 

any suggestions?

 

thx Olli
