You appear to be using the /classic/ folder as your custom template. Unfortunately, if you do that any changes you make will be overwritten by future upgrades/updates. Check the contents of includes/languages/english/classic/index.php. If that doesn't exist, check includes/languages/english/index.php.
If you did create a custom template, did you go into the admin and select it from the pull down menu under tools->template selection?
