This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

One Click Plugin Updater


Having grown to far exceed it’s original aim – to provide easy plugin updates in WordPress – this plugin now deals with various aspects of plugin (and theme) installation and updating. Note that version 2.0 comes with a lot of new features, and, probably, new bugs. The previous version (see the “Other Versions” link to the right) is quite stable though.

Feature Overview

  • Single-click plugin upgrades in WP 2.3 and up. The techniques that this plugin uses are slightly different from the built-in plugin upgrade feature in WP 2.5, so it’s possible that on some blogs the plugin updater works and the built-in updater doesn’t (or vice versa).
  • Upgrade all plugins with a single click (only in WP 2.5 and up).
  • Visually identify plugins that have update notifications enabled. They get a yellow-gold marker in the “Plugin Management” tab.
  • Quickly determine if there are any pending updates and how many plugins are active. This plugin displays that information right below the “Plugin Management” headline.
  • Configure how often WordPress checks for plugin and core updates, which module is used to upgrade plugins (this plugin or the built-in updater), and other options. See Plugins -> Upgrade Settings.
  • Easily install new plugins and themes (be sure to read the notes below). The plugin adds two new menus for this – Plugins -> Install a Plugin and Design -> Install a Theme.
  • Delete plugins and themes from the Plugins/Themes tabs.
  • Compatible with the OneClick Firefox Extension (up to version 2.1.2 of the plugin). Later versions use a new, improved FF addon : One-Click Installef for WP
  • Global plugin update notifications.
  • You can disable update notifications for inactive plugins.
  • You can hide the little update count blurb displayed on the “Plugins” menu.
  • Now with extra safety – uses the WordPress nonce mechanism for almost all tasks.

Important Notes

Currently this plugin only uses direct file access to update and install plugins/themes, so you’ll need to make the “/wp-content/plugins/” and “/wp-content/themes/” folders writable by PHP for this to work. See Changing File Permissions for a general guide on how to do this. Eventually the plugin should use the new filesystem access classes introduced in WP 2.5.

If something doesn’t work, you can enable “Debug mode” in Plugins -> Upgrade Settings. This will make the plugin display a detailed execution log when it tries to update or install another plugin.

A note for plugin developers – when performing an upgrade, this plugin will first deactivate the target plugin and call the deactivate hook, if any. Then it will download the new version. If everything goes well, the new version will be then activated (activate hook will be called, if any). This is different from how the built-in updater works – it doesn’t call the deactivation hook.

Additional Requirements

  • The CURL library installed or “allow url fopen” enabled in php.ini or WP 2.5 and up.
  • The plugins directory needs to be writable by the webserver (if you plan to use the upgrade/installer features of this plugin). The exact permission requirements vary by server, though CHMOD 666 should be sufficient.

To install the plugin follow these steps :

  1. Download the file to your local machine.
  2. Unzip the file
  3. Upload “one-click-plugin-updater” folder to the “/wp-content/plugins/” directory
  4. Activate the plugin through the ‘Plugins’ menu in WordPress

That’s it.

Contributors & Developers

“One Click Plugin Updater” is oopbron sagteware. Die volgende mense het bygedra tot die ontwikkeling van hierdie uitbreiding:




  • Fix (probably) a rare issue where the update would fail with “Invalid argument supplied to foreach()…”


  • The correct menu icons now show up in the Ozh’s Admin Menu. Previously the updater plugin would have the default icon due to a (still unresolved) bug in Ozh’s plugin.
  • Hiding the update count blurb thingy works again.


  • There are no release notes for this version


  • Maybe fix a situation where redundant update notifications would still show up after an update.


  • Fix some possible post-upgrade issues.


  • Partial compatibility with WP 2.8
  • Finally fixed mixed update highlights. Now they work 100% correctly at least in WP 2.8.
  • Fixed a mysterious issue where some update notifications wouldn’t show up.
  • Fixed the bug where updates would show for deleted plugins.


  • Fix a conflict with Ozh’s “Better Plugin Page”
  • Fix highlight bars not displaying for active plugins (finally)

    (hopefully) Fix : Some cases of “can’t create temporary file” errors.
