Duplicate Page Title

[PeggyPinup]

It appears whenever a customer is logged out of my site, the page title (in the browser tab) says “Customer Login” no matter what page they are on. As soon as they are logged in, page titles work as expected. Any ideas on what could be causing this?

This can happen if you somehow added an extra 'login' form on your layout.
If that's the case, you can see in Login.php, you have a  _prepareLayout function that sets the title of the page.
The way to proceed is to duplicate this PHP and comment this function.
