Currently, there are 20 language packs for DJ-Classifieds available.
You can find them all here: https://dj-extensions.com/downloads/cat_view/130-dj-classifieds/138-language-packs
Once the language pack of the chosen language is installed, the component will use it automatically if your front/back-end language is set to the corresponding one.
Please note that the component's language pack you downloaded may be outdated and you may need to add missing language constants to it.
You will know that language pack is missing the latest language constants if you see on your site texts like:
COM_DJCLASSIFIEDS_SOME_TEXT_UNAVAILABLE_IN_COMPONENT_LANGUAGE_PACK
or
MOD_DJCLASSIFIEDS_MODULE_SOME_TEXT_UNAVAILABLE_IN_MODULE_LANGUAGE_PACK
In such a case, please do as follows:
1. Copy the missing language constants (especially the ones you see on your site):
a) (front-end component texts)
(where xx-XX is your language code)
b) (back-end component texts)
2. After copying, translate them from English to your language.
3. Do the same for module DJ-Classifieds language files if there is a need - paths to module's default English language files are:
The corresponding paths for translated language files are:
Joomla offers the "DEBUG LANGUAGE" option , which helps find bugs in the translation if it is not working properly.
