Unable to login – blank white screen with "pageok" in upper lefthand corner

I was creating a website on wordpress (using a wordpress template but can’t remember the name of it) & when I returned to continue editing it (was still up on my screen, never logged out), I clicked the pages tab & it refreshed & showed a white screen with “pageok” located in the top left corner of the screen. So, I clicked the backspace bar & it took me back to the appearance page but it would not allow me to do anything other than that. Every time I tried clicking any other tab on the screen (pages, posts, etc.) it would take me to “pageok”. I thought maybe if I logged out of wordpress & tried logging back in, it might would correct the problem. So, I did that & now when I attempt to sign in I receive the “pageok” screen & I am unable to attempt to enter my username & password. My site is hosted at website palace which seems to be running fine. I am able to log in to one of my other wordpress sites which has a different username & password so I am certain that wordpress is not just down at the moment. Please help me log in to edit my wordpress site at shear-wood.com/wp-admin/. I am unable to even view anything at this point. Thanks in advance!
