Thanks to all – problem resolved. It was rectified by web hosting service.
Thanks folks for your suggestions and assistance – good news is I’m making great progress! My issue now is that I cannot access my site if I type the URL into my browser. I get the following error message “Cannot find block ‘__global__” Any idea what I’ve done wrong? Thanks.
Thanks to Gov and Stacey for your responses. I have progressed somewhat since your responses. My issue now is that I cannot log in to the admin area to install/upload a theme. How do I access the admin log-in window? I have a WordPress username and password. Thanks.
