[educlean + WP 3.0] Profile box+ translation + widget issue

Hi me agin still with edublog.

My config for this site :
=================

WP3.0 no buddypress
fr_FR hardcoded in wp-config.php
no extension activated,
site adress : http://horse-village.org

MUplugins yet installed :
================
WPMUdev notifications,
additionnals tags
global footer content
login image
post indexer
widget-recent-global-posts.php

theme
=====
Educlean 2.1.3
Test localization activated in function.php
fr_FR.mo in language folder

Issues :

1 - Translation dont apply. serveral termes translated even without the mo file as in the profile box content now
2 - the sidebar widget still dont appear (as in first attempt), with or without fr_FR.mo installed, even in compatibility screen mode
3 - several text are not in po file (especially the one on default "more feature" page, and "currently powering" that I hardcoded, "join us here" and the profile box content)
4 - where the folder /files/ is supposed to be, since my server refuses the folder creation for service pics ? [solved]

Currently the mo file is not in the folder, there is a widget on each widget place, the meta one in sidebar.

/me crying
help ?
