There's no fallback for missing translation phrases, thus all translation files have been supplemented with missing phrasess after moving hardcoded error messages from htmly.php
Created Gujarati translations. However, it seems it may need refining based on the actual en_US file corrections. I will work on that and update Hindi one as well, and hopefully the other ones too.
The file /system/admin/views/import.html.php needs the tags/codes corrected.
