I'm locked out of admin

i am locked out of my admin- i changed my password an that is not the issue- i am getting WARNING CANNOT MODIFY HEADER blah blah blah and something about a php plugggable
can a support person please email me at [ email redacted] so i can email you my login and a screen capture- i had an “ODESK” person working on the site BIG MISTAKE and i think she has hacked the site.
