Network option doesn't show up under tools

I can’t get the network option to show up in the tools menu either. I upgraded a couple weeks ago from 2.9.2, and now I’d like to do the multisite option.

I’ve tried

define(‘MULTISITE’, true);

define(‘WP_ALLOW_MULTISITE’, true);

define(‘WP_ENABLE_MULTISITE’, true);

in my wp-config file. All of them, and all of them individually, just above the That’s it line. On separate lines like above.

I’ve tried editing my wp-config lazy like, with all my plugins still enabled, but I’ve also disabled all of them, and it didn’t make a difference.

I have bluehost, and some people say you can’t do multisite on it, but others say they have and it works. I was able to add the wildcard subdomain.

I can’t access the httpd.conf file to add the serveralias line. Some people have said you can use your .htaccess file to override, but I haven’t seen any explanations on how.

Also, I’m not sure if the network option should be showing up before I get all that done anyway.

Thanks.
