I'm at a loss; I've tried everything I can think of & still no "network" under tools. I was able to successfully create the A host in the DNS with the *. I followed the WordPress installation. Edited the wp-config.php file, even tried multiple things there. I removed WordPress & installed WordPress MU (don't do this LOL), and resorted to downloading the 3.0 and manually installing. Previously, I had just upgraded to 3.0 but not from WordPress MU, just WordPress (finding there were 2 kinds took some time to figure out as well).
I'm tired, so maybe not recalling what else I've done, but whatever logical step that should be done, I tried it. I'm using the default BuddyPress theme, and I have now upgraded the default theme. Still, nothing. Hmmm, I haven't tried it without the BuddyPress theme though. I could not get BuddyPress to work right using another BuddyPress theme.
Oh, I remember; I also have my blog in a subdirectory folder (meaning the WordPress files are not separate from the main index file and such but they are not in root). I read that may be a problem, so I backed up my root files, moved them and installed my WordPress there. Nothing (meaning my site worked as it did prior to moving to the root; still no network under tools).
I disabled plugins and whatever else. Everything is the same. No network. :( I'm hosting with godaddy (don't judge lol).
I'm looking to do subdirectories, multiple blogs.
