In the Joomla install, it suggests that I turn off output_buffering. I had a look in /etc/php5/apache2/php.ini file (I'm running Ubuntu 10.04 LTS), and noticed that it is set to 4096 (presumably by ISPConfig as the default value is off). I wanted to check with the guru's here before I went and set it to off, because there must have been a good reason why you set it to 4096. My VPS has 512M memory allocated to it, and plenty of bandwidth. Should I do what Joomla is asking? Cheers, Nap
ISPConfig does not alter the php.ini at all, so the default settings yopu talk about are the Ubuntu defaults and not related to ISPConfig. If you want to turn off output buffering, then turn it off and restart apache.
