Did you read what that part actually said?
it did not say if it was in a folder.
It said if it is in a folder and you run it off the root.
mysite.com/wordpress/ <– all your files in here
mysite.com <— your blog.
If this is what you have, then you are out of luck.
If I go to yoursite.com/whateverfolder/ and that is where you are installed and that is the home address of your blog, then YES you can install a network.
you can’t domain map tho.
Yes, I most certainly read that. I should have specified that I was running it off the root. I installed it this way following the suggestion of a WordPress book author who indicated this was a more secure way to install WP. Alas, he did not mention that multisite would then not be possible. I wanted to be extra sure I needed to reinstall everything now, so thank you for your clarification.
AI should add that after posting here I visited your site and downloaded your ebook on multisite install, where you speak to this issue — too bad I didn’t come across that prior to the installation.
Which book? I can give the guys a heads up if it’s the one I’m thinking of.
I am writing a review of the book for Graphics.com and have the author’s email address, so I will be mentioning this to him. Thank you for your offer, however.
