Permalinks Not Working on Root Site ONLY

Did they ever work?

What’s in your .htaccess?

Thank you for responding. I’m sure they did work when I first installed and activated multi-site. I dont initially recall it though because there wasn’t much time between the install and importing of data. My htaccess only contains what was given to me at the time of activating mutli-site:

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

Okay, just so you know, it’s VERY important to make sure that permalinks worked BEFORE you turned on Multisite.

What plugins are you running? I know they’re all the same, but I gotta ask.

Sorry for the delay. I was seeking help from a colleague but so far no luck still. The plugins I’m running are:

All in One SEO Pack
BackupBuddy
Banners-manager
cforms
Gravity Forms
Image Widget
Network Shared Media
WordPress Download Monitor
WP Mobile Edition
WP Smush.it

@erica,

Can you try resetting your permalinks on the main site? Save them as anything other than what you have them set at, next save them back to what you want, then check and see if they work.

Thanks for the responses. I’ve been working with WordPress for a very long time so I went through all the motions that are expected and nothing worked. I finally figured it out with a colleague. Our boss who setup the staging server setup WordPress multisite on a subdomain. As soon as I started adding subsites the permalinks went haywire as did a couple other items. I had to restart the project on a single domain and now everything is fine.

We did determine a sort of hack solution though. Not sure how legitimate it is but it worked for the time being. If anyone else requires setting up WordPress multisite on a subdomain, modifying the wp-config file as so seemed to make it work again:

Change
define('SUBDOMAIN_INSTALL', false);

to

$url = $_SERVER['REQUEST_URI'];
$url = explode('/',$url);
if($url[1]=='subsite1' || $url[1]=='subsite2') { //Define each sub-site path name
   define('SUBDOMAIN_INSTALL', false); //subdomain
} else define('SUBDOMAIN_INSTALL', true); //mainsite
