Some of the strings appear and are translated. But not on the front end showing up. So I don't know what it is.
Also there is a new issue coming up. When you are on a product and change then to English it shows a page 'no results'. Do you refresh the page then, then it loads the English version of the product.
It feels like there are multiple issues on this website.
I understand the issue you're having. This type of issue most of the time gets solved after saving the permalink structure. Please follow the steps below and I hope it will help.
- Make sure that the product is translated properly and a unique slug is defined for the product.
- Please go to "Setting > Permalinks" from your WordPress Dashboard
- Scroll down to the "Product Permalinks" section and set the structure to "Default"
- Save the changes and clear the caches from your site.
After that, open the product in the frontend and switch to the secondary language. I hope the translated product will appear properly. It would be better if you could share the link to the product in the next response.
Please let me know if that helps or if you need further assistance in this matter. I will be happy to help.
