Locked out of password protected pages

I’m not sure this is an issue the the All-in-one security plugin, but it seems like the most likely culprit.

I’ve created a password protected page. When I am logged into the sited, it works fine. If I am not logged in, after I enter the password, I get a message that says I don’t have permission to view the page. Annoying!

Could this be a setting in AIO Security? If so, were would I look?

Thanks.
