Hi Yannick, for some reason it's not possible to find and translate any files within the directory 'internals2' using the Online Editor. For example I would like to translate this file: http://www.php.net/manual/es/internals2.preface.php (internals2/intro.xml) but I can't find it. I think the problem affects all the languages.
Thank you! -- Yago Ferrer
