We have fixed the entire upgrade system and now re-writing few things and also improving the interface! With the improved upgrade, Pligg users of versions 1.x; 2.0.0rc1; 2.0.0rc2; 2.0.0; 2.0.1; 2.0.2; 2.0.3 will be able to upgrade to Kliqqi 3.0.0
The updates will be added to the download package as well as a separate compressed install folder ready to download, along with detailed explanations and guidelines. The interface will better during the upgrade. During our work on Kliqqi CMS, we changed some icons and images and added missing CSS and js files as well as updated some third party files; those will also be copied over.
The new and fixed upgrade system will be posted in the next couple of days. Thank you for your patience!
