Plugin has been removed from WordPress.org
This means that a plugin is no longer available to install from WordPress.org. Plugins can be removed from WordPress.org for a variety of reasons, including that the author intentionally stopped its development or converted it to a “paid only” plugin. A plugin can also be removed if it violates WordPress.orgs terms of service or if it contains vulnerabilities. If it contains vulnerabilities, it may be restored to the repository within a few days. As a general recommendation, unless you are familiar with the code in the plugin, we suggest that plugins that have been removed from the WordPress.org repository are removed from your site.

<strong>The Plugin "Plugin Name" has been removed from wordpress.org.</strong><br />It may have compatibility problems with the current version of WordPress or unknown security issues.
Resolution
In most cases, we recommend removing the plugin and finding a similar plugin that is being actively maintained. Some hosts pre-install some plugins on all new WordPress sites, so if you have a plugin installed that you have never used, and it is no longer available on WordPress.org, it is best to remove it.
There may also be rare cases where a plugin you have from another source shares a name with a WordPress.org plugin, so if you know that is the case, it would not be necessary to remove it.
