Hello community ;
Several changes were made in the trunk between 11 and 12 July 2011 . If you are using a previous version/revision of i-MSCP, and that you have used the softwares installer, we invite you to backup the /var/www/imscp/gui/software directory before running the update script. After update, you will have to restore the content of the directory into the new /var/www/imscp/gui/data/softwares directory and execute the /var/www/imscp/engine/setup/set-gui-permissions.sh script to fix the files permissions.
Also, if you are using your own script to update your installation of i-MSCP, we invite you to check the INSTALL file for your distribution and update your script according the changes that you can found in it.
