Hi. I've been dropped in to updating content on several wp backed sites and I've only been using wp for less than a week! I tried logging into one of our sites today but noticed the dashboard was different...for instance, there wasn't an 'appearance' option. So while looking into that I realized I had loggied in via wp-login and not wp-admin. SO previously, when I logged in the first time today I tried to login using wp-admin (it actually brought the page up), I'd input my info but the page would just reload, with no error message, simply prompting me to reenter my login info. So I played around and got to mysite.com/login-wp and got in that way.
But now I see I need to get in on the admin side and now when I go to mysite.com/wp-admin it loads but redirects to this:
the only changes i've made is i changed the password to our wp account as well as our hosting account.
