File or directory not found.

Hi, when some of my customers are trying to add a product to the shopping cart they receive this error:
HTTP Error 404 - File or directory not found.
Internet Information Services (IIS)

I receive a copy of the following email every time this happens.

This is an automated response sent from SalesCart

Security Error: The referring URL could not be determined due to security
measures implemented on the computer. To prevent this in the future,
include path.asp in all your product pages or disable the checkpost
feature by opening checkpost.asp in the cgi-bin folder and setting
emailErr to 3.

Order Number:
Item Number:
Posted Price: 11.95
Actual Price: 0

Posting URL: ../default.htm
Browser: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR

What exactly should be done to correct this to allow my customers easy shopping again.

Thanks

Hi,

Yes, I have been able to reproduce the issue. The same thing is happening on my personal computer when my Norton Internet Security is enabled. I receive the error as stated above and the address in the web browser shows :
http://www.teasemetoys.com/default.htm.

If I hit the back button by my address bar, it backs up to the page I was ordering from no problem. It shows nothing is in the cart and then when I view the cart it shows the item I was trying to add.

If I disable the Norton I have no problem with any of this. The site works as it should.

Any ideas?

Thanks Jenny
