Hi,
make sure you have installed PHP-APC package (Egroupware 14.2 strongly relies o APC and Zend Opcache)
if you’re running DEBIAN just "apt-get install php-apc"
if you are under non DEBIAN-based distros use the php pear command
(it should be something like “pecl install apc” if I remember well)
then add to /etc/php5/cli/php.ini
apc.enabled = 1
apc.enable_cli = 1
Hope this help
Filippo
