Yes, you must change <!--WIZD_INSERT_CLIENT_CHARSET--> to: iso-8859-1 including <!--WIZ... ...ET-->
delete: <!--WIZD_INSERT_CLIENT_CHARSET-->
insert: iso-8859-1
do you change the following files too?
wizd.conf:
flag_read_mp3_tag false
flag_filename_cut_parenthesis_area false
flag_filename_cut_same_directory_name false
line_music.html:
change WIZD_INSERT_LINE_MP3TAG_TITLE_INFO into
WIZD_INSERT_LINE_FILE_NAME_NO_EXT
Its realy important to disable in wizd.conf (don't remark with #):
client_language_code disabled
server_language_code disabled
after that changes, its better to restart the wlhdd.
Then the directory and file must be showing correct.
