What k-OutDated Checker (k-OC) Does

k-OC stands for k-OutDated Checker. k-OC scans automatically, twice a day, all your installed plugins against the WordPress Plugin Directory for outdated plugins and email an alert for immediate update.


k-OC got its start when I had to maintain a lot of WordPress installations which their owners didn’t care much about maintenance and security.

Included Languages

  • English (default)
  • Greek (el)

If you want to help out, I have included the .pot file in /language folder. You can send them to nbran@kanenas.net


  • This is how the email alert will look like if plugins are not up-to-date.


After downloading and extracting the latest version of k-OC:

  1. Upload the folder k-outdated-plugin-checker-k-opc to the /wp-content/plugins/ directory.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. That’s all!


I have activated the plugin. Now what?

  • You don’t have to do anything else! k-OutDated Checker will scan all your plugins against the WordPress Plugin Directory (twice a day) and alert the administrator of your website (by email) if at least one plugin is outdated.

Sends an e-mail saying that there’s an update available for every single one of our website’s installed plugins, including k-OutDated Checker (k-OC) itself. There are currently NO updates available for ANY of our website’s installed plugins. In summary: this plugin cannot correctly determine whether *itself* is up to date. Uninstalling.
