When you attempt to install themes or software on your phone, you probably have encountered certificate errors such as "Certificate Expired" or "Certificate Error." This certificate error is the result of Symbian Series 60 security measures that were introduced. These measures prevent older software, themes and applications from being downloaded. You can take simple steps to fix the certificate error and install your application.
