Missing / for newly created websites

What’s your ReWrite base in your .htaccess?

What are your network settings in your wp-config.php? They should be like this:

define('WP_ALLOW_MULTISITE', true);
define('MULTISITE', true);
define( 'SUBDOMAIN_INSTALL', false );
$base = '/';
define('DOMAIN_CURRENT_SITE', 'domain.com' );
define('PATH_CURRENT_SITE', '/' );
define('SITE_ID_CURRENT_SITE', 3);
define('BLOGID_CURRENT_SITE', '3' );
define('WP_ALLOW_REPAIR', true);

Rewrite:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]
</IfModule>
# END WordPress

And using the above wp-config entry, it still spits out the same problem.

Somewhere in there you’re missing a / obviously. But you knew that ??

In your database, look in wp_sitemeta where there should be a basepath (I think that’s where it is…). That too should be /

Check your wp_blogs table. There should be a column for domain and one for path. path should start with a slash (/) or contain only a slash (if it is the root site).

If those path is missing the first slash, you’ve misconfigured something.

@ ipstenu
Couldn’t find basepath – but everything that should have been a / directory was.

@tim
Checked wp_blogs, and added a / to both domain and path. Created a test blog, and had the same issue. / was still not being added upon the creation of a new blog.

wp-config file – go check it. Look for base=”/”

@ Andrea_r:
I’m guessing the base=”/” you’re talking about is the same as the one ipstenu provided in the wp-config example code? If so – it’s already there.

Have you modified Core files or are you using a fresh download of code from www.ads-software.com?

If a slash is missing when you create a blog, something has changed either in Core files or in your configuration. If you can, set up a fresh install (entirely new database, entirely new download from www.ads-software.com) and see if you can recreate the error.

@ Tim
Fresh install, fresh database – I never modify core files.

And absolutely no plugins? Because I can’t reproduce this.

Are you adding new blogs from the frontend or the backend? (yes, it could matter)

And what webhost? Some have crippled multisite installs if they detect you’ve turned it on.

Edit:

Fresh install,

you neglected to mention you were running Buddypress with a custom template. Yes, it totally matters. A fresh install means no plugins or new themes.

Disable BP. Go to Twenty Ten. Create a blog.

Ok so if the SQL tables appear as they should, and wp-config appears as it should, then can I safely assume that it is a Buddypress issue? I would like to get this solved without having to strip anything out that is currently in place, and if I can get a sort of “maybe this is where you should be looking” kind of directionality on this topic, that would be greatly appreciated.

You can only assume it’s Buddypress if you turn off the plugin and it magically works.

Where in the WordPress files does it draw the signup form from? And when creating new sites multisite, is it supposed to add the database name to the new site name?

BuddyPress overrides the default signup form. Without plguins, it;s at wp-signup.php on the front end, or under Super Admin -? Sites -? Add Site in the backend.

And when creating new sites multisite, is it supposed to add the database name to the new site name?

AHA! No, it does not. This is the frist I;ve seen mention of that, and THAT is a well-known and reported issues.

You;re on Dreamhost, right? And used the One-click option? Scroll down in wp-config.php and see where they added all kidns of crap including another base line with your db name.

Remove that line.

Bloody brilliant.

Removing:
$base = DB_NAME;

Corrected it completely. @andrea_r – Thank you so very much!
