Hello. I have installed a ready-made theme and have just notice it doesn't contain a single.php file. Tried clicking one of my posts on the homepage and got a 404 - presumably because there isn't a page for it.
I tried supplementing another single.php which I figured I would just customize, but that didn't work either. When I wrote my posts, I clicked checked out the preview and it looked OK so I guess there must be a page somewhere.
Anyone have any idea what I should do? (I'm a total newb as you may have guessed.)
