Hi, I'm using ISPConfig 18.104.22.168 on a Ubuntu 12.04 server with Apache2. I'm trying to get APS installations to work and I'm encoutering the following issues: For most of the packages listed in Sites > APS Installer > Available packages, clicking on the name won't do anything but display the loading window for a brief moment. Even those which actually seems to work up to the pre-installation configuration screen end up with an Installation_error message in Sites > APS Installer > Installed packages. Tries to remove an installed package (whose installation failed) also end up with an Installation_error message. For security reasons, Apache is using a http_proxy, but the package list is updating fine, so I don't think the problem comes from that. When an APS Package is installing (or at least trying to), its database is created but not its files. I tried to display a more useful error than Installation_error by setting PHP: $conf['log_priority'] = 0; in /usr/local/ispconfig/server/lib/config.inc.php, but the file /var/log/ispconfig/ispconfig.log remains empty. Could you please help me to resolve this?
