Ada WPMU Sitewide Feed Plugin

Only if you install WPMU/ WP 3.0 as subdomain installation when you installed WordPress, you will be able to have feeds like “yourdomain.com/full-feed/”. When you install WPMU/ WP 3.0 into a subdirectory installation, your feed url will be something like “yourdomain.com/subdirectory?wpmu-feed=full-feed”.

wp-config.php should have either of the below constants defined and set, in order for the plugin to detect its a subdomain installation.

define(‘SUBDOMAIN_INSTALL’, true);
define(‘VHOST’, ‘yes’);

If your feed is working and it validates, including it in RSS Widget to show on your site does not actually show the entries, then follow this:
You must disable your cache plugin to cache the feed as a static page.
If you are using W3-Total-Cache plugin, add your Feed URL (relative path): to the Never cache the following pages: section under Page Cache Settings. Ex. “/full-feed/” and make sure to clear empty all caches.

disable_static_page_cache_for_feeds

The reason is your cache plugin makes the cache of the feed [which has a Content-Type: application/xml].  But after it is cached, when the browser requests, your cache plugin deliver the already cached static file, which now is delivered with Content-Type: text/html].  This causes the RSS Widget to not recognize the feed.

Current version: 0.5.2

Description:
This plugin creates four (4) seperate RSS 2.0 feeds from posts, comments, pages, and one combined [posts & pages] across all blogs on your WPMU powered site. This will skip the first post, comment, and page of a blog; also will not include spam and deleted blogs.

Instruction:

WPMU:

Unzip and upload to mu-plugins directory.

WP 3.0:

You can either create a directory called “mu-plugins” inside the /wp-content/ folder and put it inside, which in turn, will automatically activate the plugin.
Or you can put it inside the plugin directory and activate it yourself.

Upgrade: Just replace the old file with this.
