final wp installation step problem

When I run https://example.com/Blog/wp-admin/install.php, it shows the follwing message. I have already entered db name etc in wp-config.php.

>
WordPress
‘.__(‘Already Installed’).’

‘.__(‘You appear to have already installed WordPress. To reinstall please clear your old database tables first.’).’
‘);} switch($step) { case 0: case 1: // in case people are directly linking to this display_header(); ?>

ReadMe documentation at your leisure. Otherwise, just fill in the information below and you\’ll be on your way to using the most extendable and powerful personal publishing platform in the world.’), ‘../readme.html’); ?>

error) ) wp_die($wpdb->error->get_error_message()); display_header(); // Fill in the data we gathered $weblog_title = stripslashes($_POST[‘weblog_title’]); $admin_email = stripslashes($_POST[‘admin_email’]); $public = (int) $_POST[‘blog_public’]; // check e-mail address if (empty($admin_email)) { // TODO: poka-yoke die(‘

‘.__(“ERROR: you must provide an e-mail address.”).’
‘); } else if (!is_email($admin_email)) { // TODO: poka-yoke die(‘

‘.__(‘ERROR: that isn’t a valid e-mail address. E-mail addresses look like: [email protected]’).’
‘); } $wpdb->show_errors(); $result = wp_install($weblog_title, ‘admin’, $admin_email, $public); extract($result, EXTR_SKIP); ?>
admin
