Our website is hosted on a Linux server here in Korea. The previous server OS version was released in April 2010, and security updates are not available anymore, which triggered the need to update to a current server OS platform. My plan to upgrade the server without a clean reinstall did not work, that's why it took me until now to get the site online again. The site runs now on Ubuntu 14.04.4 LTS server edition, which will be supported until April 2019.

Please let me know if you experience any differences or difficulties in using the site. Thanks.
