When you try to use our online store, you receive a message similar to the following:
files.cssincorp.com is the accepted referrer.
is not a valid referrer
Refering Site Authentication Failed!
This is caused by Norton Firewall, Norton Internet Security, or other firewall program that is stripping the referrer information so that it cannot be passed for authentication. You will need to add a rule to your firewall for files.cssincorp.com and permit referrer information or permit the passing of information about visited sites. In Norton Internet Security, this is located under the Advanced configuration settings for Privacy. See the help files for your Norton software or other software for more information on this procedure.
