In short, I've deleted the standard 'blog' page that comes with pagelines (accident) then permanently deleted all pages in the trash (purposeful) which deleted the blog page (accident).
I've attempted to get the page back by:
1) Creating a new page called blog
2) Simply creating a post and adding the category to the menu header
Neither one of which works. I can create a new page called "blog"; however, I am unable to assign the blog page template to the page.
So, how do I fix this (not-so-little) problem? I searched and it appears that no one has had this before (or everyone simply knows how to resolve without asking!).
