Started to test to install several Applications using the Application Installer of ISPConfig and must say that most are failing in some point. 10 installation tried and only 1 get success to really work, means 99% because the Admin account is missing. That apps is Magento. All other Apps just giving an Server 500 Error if installation were complete or even the installation failed. Ok, that maybe could be of an problem with my Modem/Router, which will be changed tomorrow because of ongoing FTP problems. And both my Server with ISPConfig and the desktop I use for to install the apps are on the Modem/Router's internal 1Gb/s switch and therefore it's possible that the failed installations are triggered from that device. That I'll know tomorrow after the change of that device. Nevertheless the amount of failed installation is just to high. Regarding Magento install, I could not find the logon for admin in that standard installation. There is the sign up windows for new user and a normal logon windows but that didn't work with username and password given by installation nor with the admin e-mail address. So, I'm really don't know the installation were complete or not.
