Hey all... I have been having issues with installing concrete5 downloaded from their site, the installed keeps erroring giving out such as duplicate database or it needs an empty database. So, i have been testing the installer and worked out how to get complete. open sites from ispconfig3 admin and choose the domain you want to install it in. change php type to mod-php, click apply and they install. make sure you either delete the database and remake it or completely drop all tables ending up with a empty ddatabase.
