Problem with Translations

[miri4ever]

I added my language variable to ACP and it shows me the text using now translated language
I added / used existing lanuage key from common.php to display translated text

But inside the chat still only the language variable is shown up but not the translated text like it is inside the common.php file.

There are no existing language keys in common.php, see here: https://github.com/kasimi/phpbb-ext-mch ... common.php

Make sure you're editing the extension's common.php language file in [board root]/ext/kasimi/mchatonlinebanners/language/en, not phpBB's common.php.
