The main Loop is not starting in a custom blog template page

I made a custom template for the blog section of my page. I even set post page to Blog.

I created a custom post type called Page Content and the posts are retrieved in the #feature div. But the main posts (written in the Posts panel) are not being shown (#blog div)

Any suggestions to solve this?

EDIT: I just saw this in the webkit inspector:

Fatal error: Cannot use object of type WP_Query as array in /home/alex/www/wpa/wp-includes/query.php on line 2555
