We developed a visualforce page and tested it with a System Administrator account and it works fine. Now we created a new "Standard User" account and try to access the same page and get this error:
Insufficient Privileges You do not have the level of access necessary to perform the operation you requested. Please contact the owner of the record or your administrator if access is necessary. For more information, see Insufficient Privileges Errors.
We tried simplifying the page completed to just the following code but the error persists:
<apex:page > hello world </apex:page>
