update language files for running project

hi guys, i use only one en_us language in one of the projects, i changed some messages phrases and language lines in “Application Language” so i replaced this file from deployment of my local server _lib/lang/en_us.lang.php with the one located on the production server but the messages do not change! any idea other than cashed on my browser? (it is not cashed, i double checked and removed all cache)

okay, i got this solved guys, simply monitored the language en_us.lang.php file after update in production of my local server and opened it with notepad++ found that file is updated ok and has the updated phrases… replaced with the live project version and it took effect ok.
