Translating settings translation is now supported in the v5.1 release. You can now translate the global values set within the chat app > Settings tab in the language pack file at /livehelp/locale/en/guest.php.
At the moment, there are two settings (the welcome message and the chat window name), these can be translated as shown below:
$_LOCALE['introduction'] = 'Hey there! How are you today?';
Live Help Name
$_LOCALE['appname'] = 'Live Chat';
These lines will be included in the language pack file from v5.1 and later. You should only translate the above lines in non-English language packs and you should leave the app settings configured as English.
Feel free to contact us via. live chat or email us at firstname.lastname@example.org if you have questions.
