Having just completed an upgrade from CE v1.9 to EE 1.14, I find that the layered navigation (left block) is missing from the search results page.
The problem is that several modules and layout XML files seem to reference this block (catalog/layer/view.phtml) and I'm not sure which module removed this block.
Is there a way I can determine the layout files which were used to render the page, and the order in which they were parsed? I tried Commercebug but it doesn't actually say which XML files are used.
