lost or changing passwords.

I keep logging on but only after I go to get a new password. As soon as I close and go back it has disappeared and will not let me back in. Does this mean that I am open to hackers to destroy all this work? I use Vantage them with wordpress.

my site is http://www.lwhpchurch.org

Now I can’t even get the backdoor open it goes straight to my site and I have deleted all my cookies again. I think that bbpress is the problem with the backdoor … not sure.
