How to add a class when the user is the admin
If you want to debug your online site, then you may want to add a class to your body if the user is admin. This way, by using appropriate css rules, you can make some parts of your site visible only to the administrator. To do so, add the code below to your functions.php:
add_filter('body_class','my_class_names');
function my_class_names($classes) {
if (is_user_logged_in() && current_user_can('manage_options')) {
$classes[] = 'admin-user';
}
return $classes;
}
And in your css, add the following:
.hide-to-visitors {
display: none;
}
.admin-user {
display: block;
}

php_value max_execution_time 60

If the error below appears when you try to update your WordPress site locally

then try to enable php_open_ssl in your wamp’s php extensions. That did the trick for me!
