Topic on Project:Support desk

I am working on a site for a client and on one of the pages Template:Q2A:module=homepage 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 Template:Q2A:module=dogs and Template:Q2A:module=cats 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

Below the edit area there's a section named "templates used on this page" (you may need to hit preview first if you're editing a section). It will give you links to the template.

However, it could be that the wiki uses a custom extension and Q2A is a sort of parser function that gets the contents from an external source. In that case, you won't find it in the templates used on this page section.
