How/Where do I edit the Header File?

There are literally thousands of WordPress themes – which means that many people won’t be familiar with your particular theme. So a link to your site where people can see the theme might result in more responses.

Try asking on the theme’s dedicated forum: http://themehybrid.com/support/

It is not our place to keep theme vendors in business or deprive them of any income that they may derive from support services.
