Page not found – when clicking on a Gallery from the album.

I’m just getting my site up and going so please excuse it’s incompleteness.

I’ve created 3 test galleries and placed them in an Album. I’ve inserted the Album shortcode into the page where I want it displayed and the 3 galleries thumbnails are present, but when you click on any one of the 3 galleries it opens up to a new page and displays the 404 message.

Here’s my site: https://bryans90.apps-1and1.com/gallery

Also why don’t you guys have a “Add FooAlbum” button like you do for the galleries?

Thanks
