Hi, I install a old version of osticket (1.3) in my site using fantastico, and I try to upgrade for 1.6 RC4, and now admin pages don't work perfectly. Where can I download a full version of rc4? Thanks
You can download the latest release here: http://www.osticket.com/downloads.php(http://www.osticket.com/downloads.php).
Unfortunately you can not upgrade from 1.3 to the latest version due to the DB/code changes. However, you can install the current version and write a small script to migrate the tickets.
