Thank you.
I took screenshot.
I manually insert user tamuxu to wp_user because there were no user but it also did not work fine.
How could I upload file ??
Thank you very much.
I modified wp-config.php file like the above link and tried to install install.php and prompted to input sitenamme user passowrd from WordPress and install started and looks completed.
Next time I tried to access install.php page, it says WordPress is already installed and MySQL database includes needed WordPress file from phpMyAdmin.
It looks login account is not created successfully.
What should I do to troubleshoot ?
