Unfiltered MU gives Administrators and Editors the <code>unfiltered_html</code> capability. This prevents WordPress MU/WordPress 3.0 multisite from stripping <code><iframe></code>, <code><embed></code>, etc. from these users’ posts. Authors and Contributors do not get this capability for security reasons.
The plugin can either be used globally for your entire MU site, or it can be applied on a blog-by-blog basis.
For WordPress MU or WordPress 3.0 multisite only. Regular WordPress already offers this feature and does not need this plugin.
Warning! This is a very dangerous plugin to activate if you have untrusted users on your site. Any user could add Javascript code to steal the login cookies of any visitor who runs a blog on the same site. The rogue user can then inpersonate any of those users and wreak havoc. If all you want is to display videos on your WordPress MU blogs, use the native <a href="https://codex.wordpress.org/Embeds" rel="nofollow ugc">Embed Support</a>, <a href="https://wordpress.org/extend/plugins/vipers-video-quicktags/" rel="ugc">Viper’s Video Quicktags</a> or any of the other <a href="https://wordpress.org/extend/plugins/tags/video" rel="ugc">video plugins</a> on WordPress.org. 
If you use this plugin your site will be hacked in one way or another if you allow anonymous users on the Internet to create blogs on your site. It’s very dangerous.
Are you still 100% sure you want to use this plugin?

Unfiltered MU

I love when plugins are so cleanly written and do their trick without hassle. Especially after 8 years of no updates. Though they should submit an update just to remove the "2 years old" warning...

Still works! March 2017

This WordPress MU/WordPress 3.0 multisite plugin gives blog Administrators and Editors the ability to post whatever HTML they want.

WP Spider Cache is your friendly neighborhood caching solution for WordPress. It uses Memcached to store both objects & page output.
It’s heroic like Batcache & Super Cache, but younger, humbler, and a born web-slinger.
It comes with:
<ul>
<li>Support for registering multiple cache servers</li>
<li>An administration interface for viewing cache data</li>
<li>Ability to flush specific keys & groups</li>
<li>Drop-in plugins for <code>object-cache.php</code> & <code>advanced-cache.php</code></li>
</ul>

WP Spider Cache

This plugin has no settings. Zero. It Just Works.
Running it on my eCommerce website and not a single problem. Faster admin, just as fast front-end as running W3 Total Cache, and I don't need to tweak settings.
Thanks @JJJ!



Just great.

When Memcache module is not loaded with PHP I get a fatal error instead of an explaination. I use PHP 7.1 and my host doesn't offer Memcache, only Memcached.

Also files must be copied manually to wp-content.

Fatal error
