Just for reference, if it helps you understand how you yourself might be able to fix this error in the future no matter what template you see it on: It happens when someone calls the template on the template page itself. That is, say, Template:Lyrics has Lyrics on it. :P

If you were to call a template on its own page and not be stopped, the template would just recursively call itself, into oblivion, like two mirrors aimed straight at each other reflect into each other over and over and over again without stopping. The message was just telling you about that looping problem because the wiki software is smart enough to stop it.
