    1.2 Upgrade Notes   
        
      1.2.1 Error Messages Upon Initial Reboot
    
            Upon rebooting after successful installation, the GTA
            Firewall UTM Appliance may display errors when accessed
            using the Web interface.  This is expected, these errors are
            generated because the browser's cache is trying to access
            files and locations that no longer apply. Click OK to any
            displayed errors and refresh the browser window to access
            GB-OS 5.1. If the error messages persist, clear your
            browser's cache.
            

    1.3 SSL Certificate Replacement

        GB-OS version 5.1.1 will install a new default security/SSL
        certificate. Some browsers, including Netscape and Mozilla,
        will not recognize the new certificate if the original has
        never been replaced. If you are unable to log on to the
        firewall after upgrading, delete the browser's cached security
        certificate, then close and restart your browser before
        reattempting remote access to your firewall.
