UPDATE: Please read first.
Ok, I’ve solved the mystery surrounding the unrecognized passwords: to log into the admin page you are a prompted by a Word Press branded page asking for a user name and a password. I assumed because it was a Word Press page, it was asking for my WordPress user name and password; unfortunately that is not the case. Instead it was prompting for my ISP access user name and password, which I tried through a process of frustrated elimination. Not exactly very clear or user friendly. I’m in to admin now and should be able to update the site myself now. I assume one I’ve made the changes that I can take the site live through the admin?
Thanks for your help and your patience.
