Page not allowed due to ACL setup

Hi,

Anyone experienced the same error as me?

*UsrSomePage is not allowed due to ACL setup for *CurrentUser. Failed rules: - Object page settings rule.

HTPP: PostClient:

I have a classic page I'm trying to open from a freedom detail. My button works perfectly for Supervisor then opens the classic page, but for any other user it doesn't. The object has no permissions declared at the Object Permission section.

Let me know if you know anything.

PS
I tried adding System Administrator to User and the button works, but I don't want to do that. Object has no permission set-up. 

Regards,
Solem A.
