Warning!
One or more of the directories must be made writeable by the webserver. You will be reminded to reset the permissions at the end of the install.
Please chmod 777 directory-name
or chown that directory to the user the web server runs as (usually nobody, apache, or www-data)
Refresh this page when you're done!
Quick fix:
chmod 777
Warning! .htaccess already exists.
A file with the name '.htaccess' already exists in this directory and I cannot write to it. Please ftp to the server and delete this file from this directory!

Installing WordPress µ
Welcome to WordPress µ. I will help you install this software by asking you a few questions and asking that you change the permissions on a few directories so I can create configuration files and make a directory to store all your uploaded files.
If you have installed the single-blog version of WordPress before, please note that the WordPress µ installer is different and trying to create the configuration file wp-config.php youself may result in a broken site. It's much easier to use this installer to get the job done.
What do I need?
- Access to your server to change directory permissions. This can be done through ssh or ftp for example.
- A valid email where your password and administrative emails will be sent.
- An empty MySQL database.Tables are prefixed with
wp_ which may conflict with an existing WordPress install.
- Wildcard dns records if you're going to use the virtual host functionality. Check the README for further details.
If the mod_rewrite module is disabled ask your administrator to enable that module, or look at the Apache documentation or elsewhere for help setting it up.";

Directory Permissions
Please remember to reset the permissions on the following directories:
You can probably use the following command to fix the permissions but check with your host if it doubt:
chmod 755
Further reading
- If you run into problems, please search the WordPress µ Forums where you will most likely find a solution. Please don't post there before searching. It's not polite.
- There is also the WordPress µ Trac. That's our bug tracker.
Thanks for installing WordPress µ!
Donncha
wpmu version:
No-www
WordPress µ strips the string "www" from the URLs of sites using this software. It is still possible to visit your site using the "www" prefix with an address like but any links will not have the "www" prefix. They will instead point at .
The preferred method of hosting blogs is without the "www" prefix as it's more compact and simple.
You can still use "" and URLs like "www.blog1." to address your site and blogs after installation but internal links will use the format.
www. is depreciated has a lot more information on why 'www.' isn't needed any more.
