It take long time since last my post.
And thank you very much for your kind suggestions on that time.
Today I ask the question below.

I installed EMLH and it moves very well.
But there is no change on defined constant words of xoops if I click to english.
For examle
in japanese of PiCal
define('_PICAL_MB_PREV_DATE','昨日') ;
in english
it should be
define('_PICAL_MB_PREV_DATE','yesterday') ;

But no change happened.
It woudl be as EMLH, or bugs of program??

And please advice how change lamguage files, if EMLH dosen't chnage it.
