How to Turn on Maintenance Mode in WordPress

Awhile ago we posted an article demonstrating how to put your WordPress site in maintenance mode by editing your .htaccess file. This may be an even easier way to turn on maintenance mode, since you don’t have to use FTP. Simply add this bit to your theme’s functions.php file:

{code type=php}
function maintenace_mode() {
if ( !current_user_can( ‘edit_themes’ ) || !is_user_logged_in() ) {
die(‘Maintenance.’);
}
}
add_action(‘get_header’, ‘maintenace_mode’);
{/code}
