Hey, I did it.
Yes you can set it up in the root of an add on domain pointing to a subdomain.
I got this message though, after the initial install screen, which you fill out the details.
What does this mean?
Creating Database Config File: DONE
Warning: Invalid argument supplied for foreach() in /home/director/public_html/p-i-p-p/wp-includes/functions.php on line 692
Congrats! Your WPMU site has been set up and you have been sent details of your login and password in an email.
It says my site is installed. Do I need to worry about this warning?
Thanks,
Tom
