Are you facing Insufficient Privilege on all pages?
I am getting a redirect to NoAccess.jsp page after login. I can't access any page.
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.
Why is this happening?
Looks like you are facing insufficient privilege because the API Only User checkbox is accidentally checked for your User. You can visit JanBask Digital Design, API Only User permission was set on Profile or Permission Set, causing login issues. If your profile has "API Only User Checked" then it's common to receive this error.
