I have zend running on a VPS with Centos. I set it up by dragging the zend library files into the httpdocs, then editing my php.ini and adding the line of code below:

include_path=".:/var/www/vhosts/mydomain.com/httpdocs/library"
This is probably not a good way of setting up Zend, but it works fine for one domain.

Now the problem is I can't use zend with another domain on the same vps. I tried to add another include_path at the end of the php.ini, but then nothing works.

For example I tried this in my php.ini

include_path=".:/var/www/vhosts/mydomain.com/httpdocs/library"
include_path=".:/var/www/vhosts/myotherdomain.com/httpdocs/library"
What could be the problem and also what is the best way to set up Zend on a VPS?

Thanks in advance!
