Have posted this at Joomla forum too, for obvious reasons: Trying to install Joomla on an ISPConfig3 vhost running on a Ubuntu 9.04 server. Have followed the install manual and uploaded the extracted Joomla1.5.15 files to the web root of the website. Have created a DB in mysql and set up the user. When I enter the web address in my browser(Firefox3.5) I get an initial joomla screen warning me to delete the installation folder before proceeding. It wont go any further until I do, fair enough. I delete the installation folder and refresh the browser, only to have a 404 error and nothing display. Any ideas were I am going wrong ? Have tried to follow the steps at: http://www.howtoforge.com/joomla_ispconfig But I think the steps could be a bit dated. Do I need to have a php5.ini in my vhost somewheres? or does ISPConfig just use the one in /etc/php5/ and if so which one do you edit to take effect on the webhost in ISPConfig?
