XF 2.2 Don't see debug output in page

[MennovdH]

I'm trying to debug some poor performance on my server so I've enabled debug mode on my staging server. I don't see any debug output though.
I suspect this must be due to something missing in my templates, but I can't figure it out.

What line in which templates should be rendering the debug output?

It's a separate URL (adds a query string), click the execution time in the footer.

Thanks Matt. Now that I know for sure what to look for, I can tell you with 100% certainty that it was not there in the default forum style.
Not sure what happened.

I temporarily switched to the default style, and now the link is there. Not ideal because the custom style uses some funky widgets that might or might not slow down the rendering.
