Head missing

I could install Userfrosting well, but all pages have the `<head>` missing in the user side. This is a sample of /account/dashboard_admin.php:

```
<!DOCTYPE html>
<html lang="en">

  <body>    
    <div id="wrapper">
```

I think that is a problem in the renderTemplate or renderAccountPageHeader functions, but I do not know which...

Also, pages spend time to load. Will this be related?
