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)
