►►มี plugin อะไรที่ไม่ใช้มันโชว์ Sample Page เวลาสร้าง wordpressใหม่บ้า

ไม่ต้องหา Plugin ครับ ให้แก้ตามนี้เลย

- ให้เปิดไฟล์ /wp-admin/includes/upgrade.php

โค๊ด:

function wp_install_defaults($user_id) {

-ประมาณบรรทัดที่ 105
- จากโค้ดประมาณนี้

โค๊ด:

-ให้ตัดเหลือแค่นี้

โค๊ด:

function wp_install_defaults($user_id) {
	global $wpdb, $wp_rewrite, $current_site, $table_prefix;

	if ( is_multisite() ) {
		// Flush rules to pick up the new page.
		$wp_rewrite->init();
		$wp_rewrite->flush_rules();

		$user = new WP_User($user_id);
		$wpdb->update( $wpdb->options, array('option_value' => $user->user_email), array('option_name' => 'admin_email') );

		// Remove all perms except for the login user.
		$wpdb->query( $wpdb->prepare("DELETE FROM $wpdb->usermeta WHERE user_id != %d AND meta_key = %s", $user_id, $table_prefix.'user_level') );
