Thank you for the point in the right direction. I'm a little nervous about this on two counts. 1. I'm new to Linux and there are many things I'm still having to learn. 2. This is a production server, which I did not set up.
I think I should do the following:
cp –avr /usr/share/pear .
chown apache:apache /var/www/vhosts/chroot/share/pear –R
Include_path = ”.:/var/www/vhosts/chroot/usr/share/pear”
Does this seem correct?
