Hi @Anonymous ,


Could you check whether your portal login account is correct? Is it the owner's account of portal?

Have you ever selected the “Enable entity permissions” in Advanced settings ?


If checked, you must create entity permissions that determine access and ownership of the records according to web roles.

If you want to add a record, you should have the privilege of Create at least.


For more information, you can refer to these docs: Add entity permissions to a web role, Create web roles for portals

Best regards,
