I can't access some databases through IWP

[IMIC]

After pulling most of my hair out, I finally got FileMaker Server 7 Advanced working with Instant Web Publishing. I made a test database and successfully accessed it.

Then I added several other databases to the server. Some I can access fine, others I can't access, and even others don't even show up.

In the FileMaker Server Admin Tool, all the databases have a status of normal.

In the Web Publishing Admin Console, only some of the databases show up, but they all have a + under IWP.

I have 5 databases working fine. Another one shows up, but asks me to login. It won't take my username and password. I activated the guest account, but it still asks me for a username and password.

From what I can see, there are no differences between the databases I am trying to host. Is there a setting somewhere I've missed? If anyone can help with this, I sure would appreciate it.
