ISPConfig 3.0.5.4p9 installer updated
This post is from 2016. Versions, commands and links in it may be outdated. The current release is ISPConfig 3.3.2p1.
Today we updated the install.php and update.php script and added a warning that ISPConfig 3.0.5.4p9 is not compatible with PHP 7 as system PHP (no problems with PHP 7 as additional PHP though). This is not an update, so no need to update existing installations.
If you use PHP 7 as system PHP (e.g. when you use the brand new Ubuntu 16.04), then please use the ISPConfig 3.1 pre release:
