This Tool Shows Removed WordPress.org Plugins You Are Currently Running
Many of us use free plugins from the WordPress.org directory to power our sites. Not all these plugins remain in the directory or get updated regularly. Thanks to No Longer in Directory, you can identify removed plugins fast. It also shows old plugins that haven’t been updated in over two years.
Not all removed plugins have security vulnerabilities. The reason shouldn’t matter in the end, especially when you are going to have a hard time getting updates for removed WordPress.org plugins. The No Longer in Directory plugin simply lets you know when the plugins you are running are no longer available on WordPress.org, so you can find an alternative solution. This is a free script.
