Theme Horse

HI all,
If you want any functions to be changed then first unhook and then customize the code. At first create a child folder and inside it create a 2 file style.css and functions.php file
http://codex.wordpress.org/Child_Themes
under style.css file import the css from the parent interface theme and under funcitons.php file first unhook the parent file and then only customize the code. For more other support than this you need to hire a developer.

Thank you!
