How to translate Smart Slider 3?

You can translate Smart Slider 3 locally on your computer!

Step 1

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.

☝️ Note: If you're translating an existing translation file, make sure you update the translations first!

Step 2

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.

Step 3


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.

Step 4

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.

How to translate Smart Slider using Loco Translate?

To be able to update your translation files using Loco Translate plugin, you will need to go to Loco Translate -> Plugins -> Smart Slider 3 (or Smart Slider 3 Pro) -> Advanced tab and configure it as you can see below:

Project name Smart Slider 3 Pro
Text domain nextend
File prefix
Template file Nextend/Languages/smartslider3.pot
Domain path Nextend/Languages/

Make sure you copy and paste the texts without any extra spaces, as that can prevent Loco Translate from recognizing the settings properly.

After that, you can manage the existing languages or create new ones at the Overview tab.

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.

How to translate the Countdown layer?

By default the Days, Hours, Minutes and Seconds text displays in English in the Countdown layer. You can translate these texts to your own language via the translation files.

Step 1

Update the language file

The first thing you should do to make the countdown layer's text appear in your language is to update the file of your language. If there's no language file yet in your language, you should create one by following these instructions.

Step 2

Translate the texts

Translate the text you want to appear in your own language. You can find a handy guide about the translation process here.

Step 3

Clear the slider's cache

Smart Slider is working from cache and you often need to clear it to make the translations show. Go to Global settings → General and hit Clear Cache.
