I am working on an existing Drupal 7 website. I have a view that has a block display. The block is being displayed on some pages in the "second_sidebar" region. The mystery is that I cannot figure out how this block is being rendered/displayed in that region of those pages! In other words, the block is being added to the $page['sidebar_second'] variable, but cannot find how it is being included in that variable.
Please take into consideration the following facts:
- The block is not being assigned to any region in "admin/structure/block
- In the page.tpl.php, there is no inclusion of that block in the page['sidebar_second'] variable
- None of the theme templates are directly rendering that block
