What k-OutDated Checker (k-OC) Does

k-OC stands for k-OutDated Checker. k-OC scans automatically, twice a day, all your installed plugins against the WordPress Plugin Directory for outdated plugins and email an alert for immediate update.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 Upload the folder k-outdated-plugin-checker-k-opc to the /wp-content/plugins/ directory.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 k-OutDated Checker will scan all your plugins against the WordPress Plugin Directory (twice a day) and alert the administrator of your website (by email) if at least one plugin is outdated.

Just install and it's ready! Does what it's supposed to do with zero effort.

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an e-mail saying that there's an update available for every single one of our website's installed plugins, including k-OutDated Checker (k-OC) itself.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.
