Maybe I’ve found the thread I need — I enabled network features two days ago. First problem I had was that the links broke in my main blog … landing page loaded fine, but all other pages produced 404s. Switched from ‘pretty permalinks’ back to default & main blog functions fine again. Next problem — new sites all produced 404s; new sites didn’t show up in Super-admin admin, but did in some other tabs. I realized I had tweaked the wrong .htaccess file — so I tweaked the right one.
Now, new sites show up in super-admin admin, but every attempt to access the new blog loads the main page to my site, rather thatn anyting to do with wordpress.
Should I uninstall WP & start over, or is there some why to fix this little mess?
