Translate bug?

Hi, I have multilanguage store by Falang component. If I copy (duplicate) product and change info text in both languages I have, I can see changes in description text in backend. But in the frontend in product listing the description text is not changed. All duplicated products has the same text inherited from first product which was used for cloning products.

Hi,

If the translations are correct on your backend, there is no reason it shouldn't be the case on the frontend too, regardless of the fact that the product was copied or not before. Are you sure that it doesn't come from a caching issue on your frontend ? Did you try to flush your website and browser cache ?

Yes. I tryed flush cash nad change browser, but it do not help.

Ok,
So it's maybe coming from your translation file, then you should probably turn on the language debug option of the Joomla configuration and display your website. At the bottom of the page, you will have a red area telling you which lines of the translation files are not correct.
Then, you'll just need to fix them.
