URGENT: Expense Report Emails come into the approver's inbox with 'You have insufficient privileges

Hi Workflow and IExpenses Experts,

All of a sudden, all of our Expense Report Emails come into the approver's inbox with 'You have insufficient privileges for the current operation. Please contact your System Administrator.' where the HTML content and expense report details are usually found in the normal emails.

How can we prevent this error from appearing in these Expense Report emails, and have the HTML body and the expense report details reappear like normal.

Note that this is only happening for Expense Reports.

Please help ASAP.  We have an P1 SR with Oracle support since Thursday morning, but Oracle support has not been able to help us to date yet with a resolution.
