WordPress MU

WordPress Mu and WordPress have merged into WordPress 3.0.

The new .htaccess for WPMu 3.0 is:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule . index.php [L]

I can't get WPMU working! What can I do?

  1. Make sure you have a wildcard subdomain setup. Go into your cPanel, go to Subdomains, look for *
    • Yes, I see an asterisk. If it's there, proceed. If not, add a subdomain called * .
    • Make sure to set the document root to your public_html folder.
    • Then see if it works. If it does NOT work, proceed.
  2. See what the error is. If it's "No WPMU site defined on this host," then try this:
    • Remove .htaccess and wp-config.php, then proceed to step 3. (Don't touch wp-config-sample.php, and if you have more than one WordPress, make sure you are looking at the correct WPMU install when removing the files.)
  3. Go back to your site and see if you get the installer. If you do, go to step 4. If not, email support@hostgator.com with all the details.
  4. Enter your Database configuration information and finish the install. Did you have success? If not, email support@hostgator.com with all the details.

Thanks Gator, I was having some MU issues (mainly not working) , and steps 1&2 changing the htaccess file, and adding the * wildcard, did the trick. I'm glad you posted this support info. Thanks -Tim
