I can never seem to remember, how to remember how to reconfigure a subdomain with plesk without looking it up, so for quick reference.

<directory /home/httpd/vhosts/ajohnstone.com>
  php_admin_value open_basedir none
</directory>

/usr/local/psa/admin/sbin/websrvmng -a

OR

/usr/local/psa/admin/sbin/websrvmng -u --vhost-name=domain.com

Also, today I learnt that you cannot attach the onmouseover event to an option element. I found this rather odd, despite never having attempted this before. I’m sure you could write a hack to attach an event.
