This plugin hasn’t been tested with the latest three 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.

Tweakr – Utility Toolkit


This plugin is a collection of common used tweaks and features – each of them can be controlled independently
It is designed as compact all-in-one solution espacially for Web-Agencies and Advanced Users with security in mind: just audit and trust a single plugin.

Visual Editor

  • VisualComponent Extension visualizes the HTML Element Structure (headings,section,p)
  • Remove the fixed-width restriction of the Editor-Area (set to 80% max)

  • No Third Party libraries required! WordPress Internal PHPMailer class is used
  • Support for TLS/SSL Connections
  • Set the Mail-From-Name and Mail-From-Address manually

  • Remove embed Rewrite Rules

Virtual Permalink URLs

  • Modern Search-Engines like Google, Bing can easier index your posts/pages
  • Only Posts and Pages are displayed
  • Password protected posts/pages or unpublished content is ignored!

  • OPT-OUT Shortcode/Button (required by GDPR/DSGVO) – also works with Caching Plugins or CDN Servers
  • IE8 Compatible

Matomo/Piwik Analytics

  • Matomo v3 Support – add your Host URL + Site ID – thats it!
  • OPT-OUT Shortcode/Button (required by GDPR/DSGVO) – also works with Caching Plugins or CDN Servers
  • Simple Page Name Option (Records the Document Title without Blog Name)

  • Settings Page Overview
  • VisualComponent Extension

  • Piwik Analytics Options

  • Analytics OPT-OUT Button


System requirements

  • PHP 5.4 or greater
  • WordPress 4.7


  1. Upload the complete tweakr folder (WordPress Plugin) to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Go to Settings -> Tweakr and configure it


A lot of the Tweaks/Extensions are already available as Single Plugins

Of course! But as a professional Web Agency it is much easier to develope, maintain and audit a single plugin instead of a set of 20+ plugins from different authors!

Why do you use your custom tracking code for Piwik/Google Analytics

Because of the Opt-Out Buttons code and the possibility to control the options via the settings page.

Thank you for this plugin. It allows to configure many WP “obscurities” that otherwise would need to be disabled by digging deep into PHP hooks. The trailing slash removal and disablement of user registration notification emails are killer features.
