Can't find blog

I am not sure if this is a wp, buddypress or multi-site issue. I am new to BP and multi-site.

I can’t find my blog page. I have a static front page. The blog is under the “Lessons” page that is in the blog sub, so the url is mysite.org/blog. The posts are under mysite.org/blog/category/ subcategory. The posts are showing up in the “recent posts” widget in the sidebar, but aren’t on the blog page. That page is blank. There are no hidden posts. The rest of the site shows fine. The other user’s blogs are showing up fine.

Any ideas what I have missed? Thanks.
