[SOLVED] Blog posts "stuck" on excerpts

I don't know what I've done, but somehow my blog posts won't display more than just the excerpts.

If I click on the blog and then click on a post - it takes me to just an excerpt from the post. There's a "read more" button underneath, but nothing more appears.

Any idea what I've done?
