Apologies for the slow reply. You can see my website fine but I couldn’t get into the back end until my webhost attached an old database to it. The problem is that now none of my backend pages correspond to what you can see because this is an old database and everything has changed. I daren’t try to update anything incase it might revert to the old version. Somehow the original website database disappeared with the update.
Ilian that link has the same problem. Again with my friends website you can see the website fine but he can’t update the back end. He has found a way around it which is going to wordpress.com and logging in via that website and he can update some things. He can’t get in through the login page though and he has lost a lot of the functionality though.
