First off, please forgive me if any of my terminology is incorrect... and thanks so much for your time.
Fresh install of wp, activated network of sites, added the blogs.dir directory, made the modification to wp-admin and to .htaccess.
At completion, I could browse to the main page of the primary site, clicking on the sample post in chrome to view it throws....
Oops! This link appears to be broken.
A bit of surfing suggested re-saving the permalink settings, did so, and now the main site pages are working fine.
Added a new site to the sites collection.
Try to view the site (by clicking sites, hovering on the subsite name, and clicking view... this problem isn't a typo), and I get that same "Oops! This link appears to be broken." error. To get a bit more descriptive error, I tried it in Firefox, and the error is 404-not found.
I'm fairly well at a loss of where to go from here, and am looking for a bit of help.
The site is located at 18.104.22.168 for now.
