The title is :A 404 Error Was Generated‏

The content:
A user at host address [OFFICE_IP_TO_HOST_ADDRESS] with IP address
[59.106.19.33] generated a 404 using the query string [59.106.19.33].

404 is a page not found error. When you delete products for example. Whatever this thing you are using to email you should contain the page and referrer if it was to be helpful at all. Check your server access logs for more helpful information.

Thank you.

As 59.106.19.33 is a Tokyo IP, unless you sell to that area you probably have someone trying use Tell a Friend to send Spam; and it's not working.

Do you have Tell a Friend set so that one must be logged in to use it?
