Just the front page loads

[Metapher84]

Hello,

I installed the plugin password-protected and enabled that admins and every one who is logged in can see the website. Unfortunately if you aren’t logged in as an admin you just can see the front page. Just if you are logged in as an admin you can see all the sub sites. So I deinstalled the plugin, but the problem is still there.

What can you do?
