High removal-risk signals

63/100

Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.

  • Long abandoned. No update in 7+ years — the top precursor to removal once a vulnerability is found.
  • Compatibility drift. Tested only up to WordPress 5.0.27, well behind 6.8.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

    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.

    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

    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.

    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!!!

    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.

    It works (tried on a multisite with many P2 instances). The main problem is that people successfully using any plugin do not vote &/or comment it to let know the real status of them.

    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…
