The plugin has been built so you can translate everything into your own language.
The simplest way to progress this is to install a translation plugin. I like Loco Translate as it’s so easy to use.
Once installed click on the ‘Loco Translate’ link in your dashboard. From there click on ‘Quick Interest Slider’.
You now have a choice to edit an existing language or add a new language.
After selecting your language for translation you will see a list of all the strings. all you have to do is do the translations.
Once you have finished send me the files and the name of your website. I will upload the translation files and give you credit for doing all the work. It’s a win-win.
The alternative is to sign into your WordPress account. If you don’t have an account, you can register here
After logging in go to the plugin translation page: https://wordpress.org/plugins/quick-interest-slider/#developers
Click on the ‘Translate’ link and follow the instructions.
