I did call my host (Godaddy), since the message advised to contact the host. According to them, they didn't see the error message when they logged in and they had no trouble updating the site with new pages. I tried to explain it wasn't the pages that I had trouble with. However, if the permissions are set by the host then I will contact the host again.
I'm not trying to be difficult when I ask these questions. I just don't understand. Thank you for your feedback.
