I'm using Magento 2.3.4

I'm looking at the translation issue for the last few days but I didn't get any answer.

I have used mageplaza one step checkout module.

Very recently I have upgraded the magento version to 2.3.4. previously I have 2.3.3.

Now the js translation on the checkout page is not working. But my custom phtml and php via translation were working fine. But only the knockout js translation is not working.

See the below screen.

enter image description here

I have checked the js translation file from pub/static/frontend/Fillme/default/de_CH/js-translation.json

On this file, the translation was reflected perfectly. Eg : "Shipping Address":"Lieferadresse",

But in the frontend, it showing like Shipping Address.

There was an i18n translation available in one step checkout module itself and in my custom language package also.

Can anybody help on this issue

  • do you try replacing it with translate="'Shipping Address'" in html Mar 17, 2020 at 16:05

Please follow this step.

  1. Clear cache.
  2. Delete file js-translation.json in the pub folder.
  3. Remove the browser’s cache in browser local storage (include mage-translation-file-version and mage-translation-storage ).

If your problem didn't resolve, please let me know.

  • @Skuynet, I have followed the above steps and it doesn't help for me. The translation file was rendered perfectly. But it is not showing in frontend

I have solved the above-mentioned issue.

In my case, the issue was in lib folder. I have tried to upload magento 2.3.4 lib folder on my local environment. And it's working. So, I conclude that, while upgrading the magento version, the library folder was not successfully upgraded. May be of any permission issue or something. I'm not sure about that.

So, in later anybody have such an issue, keep this step in your debugging scenario.
