 * Hi!
 * I edit the file l10n.php on ../wp-includes/l10n.php. I want to ask if when the
   wordpress updating again, l10n.php will be affected?
 * thanks!

 * Yes, it will be updated and you will lose all your customization.
 * Further, messing with the core file may cause issues with:
    – plugins – themes–
   security
 * In nutshell, its not a good idea.

 * I only added a code, not really customizing the file. I am really having problem
   passing a value on $locale, that’s why i add the code on l10n.php file. Can you
   help me with this? 🙂

 * Sorry. For the reasons I mentioned in my previous reply, I would not mess with
   the core files.

 * NP, I think i found a solution anyway, putting my code on wp-config.php and passing
   a value on $locale there.
 * wp-config.php will not be updated right?

 * It should not be. However, if you haven’t already done, always backup everything(
   including your database) before doing any actions, just in case something really
   goes wrong.
