Get Page Not Found Error on exhibition pages

I was told to open a new thread to get my question answered. With the Gallery Theme when I create a new exhibition it shows that it's created. It creates the following link: but then when the link is visited I get the following message: Sorry, we can't find the content you're looking for at this URL. Please try selecting a menu item from above or to the side of this message to get where you'd like to go.

Yes I did re save the permalinks but that didn't help. I even changed the permalinks around but to no avail.
