Stuck on maintenance mode

Question

I put my site in maintenance mode using this hook in functions.php,

function activate_maintenance_mode() {
    //If the current user is NOT an 'Administrator' or NOT 'Super Admin' then display Maintenance Page.
    if ( !(current_user_can( 'administrator' ) ||  current_user_can( 'super admin' ))) {
        //Kill WordPress execution and display HTML maintenance message. 
        wp_die('<h1>Sitio en mantenimiento</h1><p>Nuestro sitio esta actualemente en mantenimiento. 
            <br /><strong>Ya volvemos!</strong></p>', 'mantenimiento');
    }
}
//Hooks the 'activate_maintenance_mode' function on to the 'get_header' action.
add_action('get_header', 'activate_maintenance_mode');

and now I can't return back to normal mode.

EDIT: The problem had to be with W3 Total Cache plugin.

Answer 1

Since you are using the W3 total cache plugin, So The HTML code will be cached in the wp-content/cache folder. So Delete Cache folder from wp-content directory.

Now remove the function activate_maintenance_mode() and check the site now...

If the problem exists , Delete the W3 total Cache Constant from wp-config.php and clear your browser data and check the site.

Answer 2

I think the code is wrong, you are basically using WP_die for super admins when you say :

if ( !(current_user_can( 'administrator' ) ||  current_user_can( 'super admin' )))

I think the correct code should be

if ( !(current_user_can( 'administrator' ) &&  !(current_user_can( 'super admin' ))))

Can you try this and let me know. Praveen
