There is a frontend static language string "New Purchase" in Emerald 10, but it was not included in the language file. The worse is, it was hardcoded in the php file as normal English words, not a language key:
line 31 of: /components/com_emerald/views/emlist/tmpl/default.php
line 31 of: /components/com_emerald/views/emlist/tmpl/warp.default.php
Could you please fix this in next release?
