Okay, I've installed PHP5 on my ISPConfig box, and it is working fine as at the command line, however the webserver is still using 4.xx, I'm guessing I've missed a config or something in apache, any pointers would be most appreciated.
If you have libapache-mod-php5 installed, your webserver shall run under php5. Please check if the php5 module is listed in the mods-enabled directory in the apache configuration directory.
I get Code: Reading Package Lists... Done Building Dependency Tree... Done libapache-mod-php5 is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 27 not upgraded.
What's the output of Code: ls -la /etc/apache2/mods-available and Code: ls -la /etc/apache2/mods-enabled ?
