WordPress Global Translator Plugin


Global Translator is a free and open source WordPress Plugin which is able to automatically translate your blog in 48 different languages:
Italian, Korean, Chinese (Simplified & Traditional), Portuguese, English, German, French, Spanish, Japanese, Arabic, Russian, Greek, Dutch, Bulgarian, Czech, Croatian, Danish, Finnish, Hindi, Polish, Romanian, Swedish, Norwegian, Catalan, Filipino, Hebrew, Indonesian, Latvian, Lithuanian, Serbian, Slovak, Slovenian, Ukrainian, Vietnamese, Albanian, Estonian, Galician, Maltese, Thai, Turkish, Hungarian, Belarus,Irish, Icelandic, Macedonian, Malay, Persian.
The number of available translations will depend on your blog language and the translation engine you will chose to use.
The most powerful features which Global Translator provides are:

  • Four different Translation Engines: it has the ability to provide the translations by using Google Translation Engine, Babel Fish, Promt, FreeTranslations.com
  • Search Engine Optimized: it uses the permalinks by adding the language code at the beginning of all your URI. For example the english version on www.domain.com/mycategory/mypost will be automatically transformed in www.domain.com/en/mycategory/mypost
  • Fast Caching System: new fast, smart, optimized, self-cleaning and built-in caching system. Drastically reduction of the risk of temporarily ban from translation engines.
  • Fully configurable layout: you can easily customize the appearance of the translation bar by choosing between a TABLE, DIV or IMAGE MAP based layout for the flags bar and by selecting the number of translations to make available to your visitors
  • No database modifications: Global Translator is not intrusive. It doesn’t create or alter any table on your database: this feature permits to obtain better performances.

IMPORTANT: I daily receive about 30/40 comments and messages containing suggestions or support requests about Global Translator. Unfortunately I can’t offer free support anymore because it requires a lot of time and costs a lot. If you need help or need more advanced features, I suggest you to buy Global Translator PRO.

Latest version (20th of Mar, 2010): global-translator.1.3.1.zip

Need support or advanced features? Take a look at Global Translator PRO!

I’ve spent a lot of time writing this code and supporting it.
If you derive some benefit from this code, please consider showing your gratitude in a more tangible way. Thanks!

Global Translator has been tested on WordPress 2.3.*, 2.5, 2.6, 2.7, 2.8 and 2.9.


  • Upload the folder “global-translator” into your “wp-content/plugins”
  • Log in to WordPress Administration area, choose “Plugins” from the main menu, find “Global Translator”, and click the “Activate” button
  • Choose “Options->Global Translator” from the main menu and select
    your blog language and your preferred configuration options then select “Update Options“.


  • Uninstall and remove the previous version and follow the Installation instructions, but if you’re upgrading from 0.9 or higher version I suggest you to preserve the “cache” directory.


  • If your theme is widged-enabled, just choose “Presentation->Widgets” from the administration main menu
    and drag the “Global translator” widget on the preferred position on your sidebar.
    If your theme is not widgetized, just add the following php code (usually to the sidebar.php file):

    if(function_exists("gltr_build_flags_bar")) { 

    After this simple operation, a bar containing the flags which represents all the available translations for your language will appear on your blog. Check my blog for an example (on the sidebar) or take a look to my Youtube Video Downloaders blog.


  • Log in to WordPress Administration area, choose “Plugins” from the main menu, find the name of the plugin “Global Translator”, and click the “Deactivate” button
