I have just followed and performed all the last instructions-directions of Izzy, member of the forum apachefriends.org
# Delete, with phpMyAdmin, the empty database wordpress that I created
# Remove, with MS_fileSystem, the directory wordpress [I deleted the 24 files and 3 sub-directories]
# Start afresh with a new download of WordPress [I reinstalled wordpress-2.7-fr_FR.zip]
# Proceed to create the database in phpMyAdmin as I outlined in your tutorial
# then, armed with the database details already created before, install WordPress again

I am back to the same “ERROR MESSAGE” quoted in Section A
Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\wordpress\wp-config.php:1) in C:\xampp\htdocs\wordpress\wp-includes\pluggable.php on line 850
