Edit Stream Text

I tried to edit the files under en-gb.com_easysocial.ini to modify the header text in stream. For example where it say '(user) created new blog post'. I edited the lines labeled APP_USER_BLOG_STREAM_CREATED_BLOG_POST to '(user) created a new article' but i do not see any of the changes taking place on the frontend. I also made several other changes to this files that are not reflecting on the site.

Thanks
Matt
