Uselang=debug
From No LJ Ads Wiki
If you append uselang=debug to a BML page, it will show the string names of the text in a given page. If it is using plain English, it is unable to be translated and the backend code should be changed to allow translation.

The uselang argument can also be used to change the text to be in a different language.
