If you have cache enabled on your site it is possible to keep the old news render. Check first in admin area Settings/Cache to see what kind of configuration you have. Then click on Cache Disabled and on Empty Cache button. Reload you frontend to see what happens. If you still have COMMENTLINK then check your language file in THEME_DIR/fs_04/languages/English.php. Search for COMMENTLINK. If you find it then the problem is not in your theme. Do all of this and contact me again.
