 * Hi,
 * I get an error installing WordPress 4.6 on IIS (Windows 2012 R2) / PHP 5.6 and
   MySql 5.6.30).
    Specifically “WordPress errore database Unknown column ‘wp_’ 
   in ‘field list’ ” by the section below on \wp-admin\setup-config.php:
 *     ```
       $wpdb->query( "SELECT $prefix" );
       if ( ! $wpdb->last_error ) {
       // MySQL was able to parse the prefix as a value, which we don't want. Bail.
       wp_die( __( '<strong>ERROR</strong>: "Table Prefix" is invalid.' ) );
       }
       ```
   
 * If I remove this section, I’m able to complete the installation.
 * Any idea?
 * Thanks in advance

 * You mean remove the section in \wp-admin\setup-config.php?
 * If so, as the adage goes, don’t modify core files. Modifications can cause:
    –
   security risks, – performance degradation, – broken plugins/themes, – you will
   lose all changes when you next update the WordPress, etc.
 * Useful codex guides:

 * Hi Tara,
 * okay, I am aware of this, but I want to know if someone is engaged with this 
   and what type of error or condition is.
    “wp_” isn’t a value and I think it’s
   still the default table prefix in a new WordPress installation.
 * Thanks for your kind cooperation
