How to translate Smart Slider 3?

You can translate Smart Slider 3 locally on your computer!

Locate the translation files

You can find the translation files at the following locations on your server:

  • WordPress Free: /wp-content/plugins/smart-slider-3/Nextend/Languages
  • WordPress Pro /wp-content/plugins/nextend-smart-slider3-pro/Nextend/Languages
  • Joomla /libraries/smartslider3/src/Languages

Use FTP to reach them. If you're looking at the zipped installers, you can find the files at:

  • WordPress /Nextend/Languages
  • Joomla /lib_smartslider3/src/Languages

Find the smartslider3.pot file, and if you're using FTP, download this file.

Creating the translation file.

To be able to create and edit the translation, you will need to have a po editor. You can find online editors, or use any downloadable editor you want. In this tutorial I'm going to use Poedit. It's free and very intuitive.

After you installed Poedit open the smartslider3.pot file. The editor interface is divided into two columns, and the first column has 3 rows. Find the Create new translation button at the bottom row and click on it.

Select the language you want to translate Smart Slider 3 to from the popup.


Poedit will create a .po file for you for translating. Here's a quick overview on Poedit.

  1. This is where you can see all texts. You can select the one you want to translate by clicking on it.
  2. At the Source text field you can see the text you're currently translating.
  3. At the Translation field you can edit the translation you're making.

To save your work, press the Save button.

Checking the translations

If you would like to view the translation you made, upload the created .mo file back to your server:

  • WordPress Free: /wp-content/plugins/smart-slider-3/Nextend/Languages
  • WordPress Pro /wp-content/plugins/nextend-smart-slider3-pro/Nextend/Languages
  • Joomla /libraries/smartslider3/src/Languages

Make sure that the translation file is named like this:, with an underscore and not with a hypen.

When you finish your translation, feel free to contact us and send us the .po file, so that we can include it in the next versions.

Updating the translation

If you're working on an existing .po file you should always update the translation. To do so via Poedit go to TranslationUpdate from POT file and browse the smartslider3.pot file to ensure you're translating the latest strings. The smartslider3.pot file is located in the same folder as your currently translated .po file.

To save your work, press the Save button.
