I have a very simple page that was working in my Customer Portal previous to the current release, but no longer does.  The page works fine in the general User environment, but when used in my Customer Portal, it no longer works.  Below is the page.  Also, my Profiles and Customer Portal have access to the page.

 Page

<apex:page showHeader="false" standardController="Product_Sales__c" recordSetVar="productsales" tabStyle="Product_Sales__c">
    <apex:form >
        <apex:pageBlock title="Update Product Sales">

            <apex:commandButton value="Cancel" action="{!cancel}"/>
        </apex:pageBlockButtons>
