Magento - Change translation don't work

I wan't to change the string:

$message = $this->__('There is already an account with this email address. If you are sure that it is your email address, <a href="%s">click here</a> to get your password and access your account.', $url);

located in the core/Mage/Customer/controllers/AccountController.php on line 345

I've changed the translation (with Notepad++) in: /design/frontend/default/my_theme/locale/de_DE/translation.csv but it's开发者_开发知识库 not working. Anything else, translated in this file, is working fine.

Any ideas? Thanks in advance!

Translations are cached so you will need to clear the cache in System > Cache Management or by emptying the contents of var/cache directory.

Another way is to use the inline translation tool that is built into Magento.

It's a strange but trivial problem still in 1.9.2.1

Put the original string and the translated one (the complete translation line) into Mage_Customer.csv (instead Mage_Adminhtml.csv) in your preferred language pack folder and the translation will work.

In bin folder run php magento cache:flush CLI command. That does the same thing in magento 2 from terminal as @clockworkgeek suggested.

Try to set locale option default on System->Configuration->General and on tab Locale Option set locale with your language translation
