Thread:Project:Support desk/find text for section Template:Q2A:module=homepage

I am working on a site for a client and on one of the pages is embedded in the page and a block of text is rendered from it. I want to edit the content of that section but I can't find where the text is coming from. Template:Q2A:module=homepage does not exits. On other pages there are and  are embedded and also showing text. How can I debug this? What other options are there for the types of page you can put within with this structure Q2A:module=

Thanks
