TOPIC:

I am looking a way to translate the contents in configuration tab into other languages. I tried to switch between the language like in the attached picture below but it saves only the 1st tab "Shipping Method Information".



Is there a workaround for this ?

The rules themselves are not translatable, because that would make it very cumbersome to administer a store with multiple languages. You'd have to take extreme care to update the rules for each language every time you change a rule.

Instead, it is possible to translate the rule names via the Joomla translation system.
Give each rule a unique name, preferrably all in uppercase and with no spaces, e.g.
You can then add a language override for AIMAR_SHIPPING_FREE in "Extensions -> Language Manager -> Overrides".

While it's possible to use a rule name of a real language and then translate this name in the language manager (e.g.), this is not recommended, as any change to the rule name (like correcting a typo) requires you to adjust all translations.

Best regards,
