Overview
Unfiltered MU gives Administrators and Editors the unfiltered_html capability. This prevents WordPress MU/WordPress 3.0 multisite from stripping <iframe>, <embed>, 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.

Apparently it still works
by Lucas Carvalho·3 years ago
I’m using WordPress version 6.0 and this plugin initially solved my problem, at least adding it as a mu-plugin.
It is well written and if necessary it is not difficult to create its own version to allow more user roles if necessary but this functionality should be implemented somehow in the WordPress core in the network and/or site settings.
Still working with WP version 5.8

My multisite network uses raw HTML, inline SVG and scripts in certain pages, but Admins trying to edit these pages, would mean the page breaks and displayed in mess…Applying this plugin took the pain out of Super Admins and Admins!
Please keep this plugin alive and updated…we need it.
Thanks
Needed More Then Ever for Multisite WP 5.0 and later
by greenling·6 years ago
I’m no php expert, but wish someone who is would make sure this plugin keeps working with later revisions.
WordPress 5.0 seemed to have removed the ability to allow unfiltered HTML with a define line in the config.php file. Hence my subdomain sites all had to have a superadmin place their paypal button scripts. Site admins could not go back and edit those pages without the script being erased.
This plugin seems to do the trick. Better yet, Superadmins can enable the plugin on a site-by-site basis.
Works great!

I have a WordPress Multisite install and found that our editors and sub-site admins could not longer embed videos in an Advanced Custom Field ( An update to that plugin changed it’s behavior ). I tried 3 different roles and capabilities editors and none of them worked. Then I tried this plugin and it fixed the problem immediately. Thanks!!!
Working with WordPress 4.9.8
by nastysquar3d·7 years ago
I have a multi-site installation with WordPress 4.9.8. A user setup as an “administrator” wasn’t able to put iframe (google maps) and script tags (embedded hubspot form) in the WYSIWYG editor without them being stripped out. Installed this plugin, all is good now.
I’m not surprised it still works even if it hasn’t been updated in years. It’s made by Automaticc. Automaticc made WordPress. This isn’t some third party garbage plugin.
