Controller Exception 403

Greetings all. For some reason, this particular exhibit has begun throwing 403 errors no matter what URL you use to get to the site. Interestingly, you CAN get to all the pages from clicking on the link to the exhibit from the Admin pages. In other words, if you click on the "View Public Site" button on the Admin pages, you are able to get to the site, and everything works as it should. If you just click on a link directly to the exhibit, you are presented with the Omeka_Controller Exception_403 that I will paste below. Help? (This is version 1.5.3)

Is the exhibit public?

Wow, thanks for the fast reply. Yes it's "public", but it hasn't been announced yet and is not linked from anywhere else.

Further info: If you attempt to go to the front page of the exhibit,

a 403 error is thrown, but if you attempt to go to a page deeper in, a 404 error comes up:

So, you seem to have a pretty complicated setup there.

You have many separate Omeka sites under the "online-exhibits-dynamic" folder, or is something else going on?

Yes, attention needs to be paid to the separate Omeka installs - it was a learning experience. We've just about an hour ago decided to start over completely on this particular exhibit, so I think the errors are no longer anything to be concerned about. We'll be bringing all the exhibits under one install of Omeka and straighten out a few other kinks along the way and we should be good. Thanks for your very fast response to my plea :-)
