, you are completely wrong. Black Star changed the link assigned to the logo (if you click on it) to a specific forum as he stated out in first post. He does not want to change the logo itself.
Black Star, please take a look at the Custom Templates article in the help. Take a look at the „Enabling the Custom Templates” section of the linked article. Has your style a non-standard template group assigned? If yes, then remove the copy of the pageHeader template from it. Otherwise I think you edited the mentioned template manually in the file system.
