I’m trying to setup the multisite feature for wordpress 3.0 on my Mac’s localhost

  • 0

I’m trying to setup the multisite feature for wordpress 3.0 on my Mac’s localhost via MAMP.

When I follow all the instructions for turning on networking via subdirectory or subdomain, either way, I get

“Safari can’t open the page.
Too many redirects occurred trying to open “http://localhost:80/”. This might occur if you open a page that is redirected to open another page which then is redirected to open the original page.”

I’ve tried everything I could find on forums:
-commenting out the define( ‘DOMAIN_CURRENT_SITE’, ‘localhost:80’ ); line
-adding this line define(‘NOBLOGREDIRECT’, ‘http://localhost:80/‘); to the wp-config file
-adding define( ‘SUNRISE’, ‘on’ ); to the wp-config
-tweaking the .htaccess file in various ways
-changing configuration settings in MAMP
-clearing cookies and the cache
-adding define( ‘SUNRISE’, ‘on’ );
-I even reinstalled wp3.0 five different times and one of those times I took all the contents out of the wordpress folder and dumped them directly into the htdocs folder as one forum post said to do.

None of this has worked. I don’t know if this is a quirk of using a Mac and using MAMP. Here is the base url for the site: http://localhost:80/
I’ve tried deleting out the :80 part in the url bar and it gets redirected back to (http://localhost:80/)
Here is my Mamp Apache document root path: /Applications/MAMP/htdocs/
(I tried this with and without the trailing slash)

What am I doing wrong?

    WordPress Multisite will not work with the port number in the URL (as stated in wp-includes/ms-setting.php).

    You’ll have much better success if you set up an Apache VirtualHost, for example;

    <VirtualHost *:80>
    DocumentRoot "/path/to/wordpress"
    ServerName wordpress.dev
</VirtualHost>

    You’ll need to edit the HOSTS file to point wordpress.dev to 127.0.0.1 (your local IP address).

    This means you can now use http://wordpress.dev in the address bar – since the server name is a standard domain format, WordPress MS shouldn’t have any problems (this is exactly how I run my set-up).
