Thanks for pointing me in the right direction on the open base dir. If you shared server is running plesk you can actually create a vhosts.conf file to disable open_base dir on a domain or sub domain level.
First off, add a file, ‘vhost.conf’ for http sites and for https sites add ‘vhost_ssl.conf’ in the conf directory.
Add the new direction options there.
php_admin_value open_basedir off
Once this has been added run
/usr/local/psa/admin/bin/websrvmng -a -v
This will cause httpd to use this vhost.conf file.
Then restarted httpd to commit the new changes. /etc/init.d/httpd restart
This issue also solves the problem for people using php 5.2.5 and are having installation issues.
