I have four wordpress installations (blogs), each on its own subdirectory. Only one is live, and I mapped its domain to subdirectory 1, so index.php and .htaccess for that first site are now in my root diectory. All good.
Now I want my second blog to go live, but how do I do this without overwriting these files from my first blog? I read Using a pre-existing subdirectory install under http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory but got stuck after re-naming the blog in settings and now have a broken site and can't change it back.
what shall I do?
