I had a WordPress site requirement where only logged in users could see the site and it’s contents. I came across this bit of code a few years ago and found it to be helpful. Place it into your functions.php and when a visitor comes along who is not logged in, it’ll redirect them to the wp-login.php page to login.

This snippet uses the the database login and password information from your wp-config.php. If you need to specify different login information, just change the DB_USER and DB_PASSWORD to [Read More…]
