I downloaded the latest v3.2.6 of iJoomlaComment component, it already have two Chinese language translations for the frontend inside (they were translated by me :P ) .

But the filenames for those Chinese language files are not correct. They were:

chinese_simplified.php
chinese_traditional.php

In such a format, they can't be automatically matched to the Joomla! site language if the later is one of those Chinese.

The Joomla! rule for Chinese language files should named as :

simplified_chinese.php
traditional_chinese.php

I had updatd the language files to latest v3.2.6 and corrected the filenames, please use my attachment to update your download area and modify the xml file for proper filenames.

Thanks. _JoomlaComment_v3.zip
