No problem about the language. I was just having a hard time trying determine which screens you where showing.
Ok, it shows both modules as enabled, but not showing in the .MODs area.
Look in your database (phpbb_modules table). You should see "Medals Control Panel", "ACP_MEDALS_SETTINGS" and "ACP_MEDALS_TITLE" in the module_langname column. ACP_MEDALS_TITLE is the management module. In your phpbb_acl_options table, "a_manage_medals" (1,0,0), note the id number. In phpbb_acl_users table, find the auth_option_id equal to the a_manage_medals.id that you noted in the previous table. I should be assigned to user_id 2, and auth_setting=1.
That will tell you that userid 2 has permission to view the modules.
