Problem with translation

Hi, Im using latest version of phplist and i have difficulties translating 3 phrases. $strPersonalLocationSent, $strYouAreBlacklisted and $strUserNotFound. I have already add them to The funny is that I have also tried to add them to defaultFrontendTexts.php but nothing changes, except strUserNotFound.
For example : change of text " Success! You should receive a message with your personal location shortly" when you add your email to change personal details (?p=preferences).
