WordPress.org publishes core WordPress updates constantly, and PHP, Apache, Nginx and updates to other plugins and themes are posted at least as often, too. This continually changing landscape represents a security risk over time.The best option in this situation is to remove the plugin and replace it with a plugin whose author is actively maintaining the code.

Key Takeaways:

  • There are many reasons why a high profile plugin may be removed from WordPress.
  • Check to see that the removed plugin does not have a security violation before continuing to use it.
  • Check if there are alternative plugins you can use to replace the outdated/removed plugin.

“Plugins can go bad if they’re not actively maintained and kept up to date with the latest coding standards.”
