It appears that you are using an outdated verson of the translation file. You will have to wait for a new version of the Spanish translation (not from me: I don't speak a single word Spanish
), or translate it yourself (which will take time).
And about your note: that's an error in the translation file, I'll have a look myself if other langages have the same error.
That's an error in on of the script files and one of the many Copy-paste frustrations.
That's why I use a dynamic system to get the script's name
@ Matti:
Check line 82 of Language.js.
Looks like you're going to need another update
