I have had issues with my WP install and was wondering if you could shed some light on it.

Specifically, in step two of install ( where the Site Title Username Email Password need to be entered - part of wp-admin/install.php)

I have experienced an unrelenting error of “Please provide a valid username”).

This install is for a new site and I have had to re-install Wordpress a number of times so it may be overlapping somehow.

My WP files are installed in a sub-directory - /home/sitename/public_html

Is it possible the install.php file is missing the public_html subdirectory and missing the usrname value for the install?
