Abrir Gmail ao clicar em um link com protocolo mailto:

Abra o Gmail pelo navegador e digite o código abaixo no console:

navigator.registerProtocolHandler("mailto", "https://mail.google.com/mail/?extsrc=mailto&url=%s", "Gmail");

Um browser de confirmação será exibido, e caso confirmado, registrará o protocolo.
É possível registar mais de uma ação para um protocolo, portanto, caso queira remover ou tornar padrão um protocolo registrado pelo navegador, acesse chrome://settings/handlers para gerenciar.

Wordpress: erro no /wp-admin/admin-ajax.php O erro nunca é informado nesse endpoint. Para ter uma pista de onde esta ocorrendo o problema, edite o arquivo /wp-includes/class-wp-fatal-error-handler.php e no método display_default_error_template insira um print_r($error); die;. É uma solução horrível, mas é o que resta quando não existe mais esperanças.
