Wikipedia talk:Lua error messages

Which script returned the error?
Hi! Say, I stumbled upon a page that has Lua errors all over it (at the moment, it's Underworld (2003 film), but it happens often enough). Is there a way to find out which script returned the error? God I hate Lua and everyone who voted for using this half-baked fiasco of a language. Primaler (talk) 10:48, 27 August 2015 (UTC)
 * The strange thing is, it works OK both in preview and sandbox, so I have no idea even where to start. Primaler (talk) 10:58, 27 August 2015 (UTC)
