Comment edit page blank “35”

Hello there ,

I have just updated my wordpress to the new 2.7. After the upgrade I tried to open the comments page to moderate the comments but all I found is a blank page with the number 35
I returned back to the dashboard where I tried to moderate the comments from there and after I succeeded to moderate couple of comments , I reload the page and guess what the blank page with the “35” appeared instead of the dashboard !!
Now I want to restore my dashboard and my comment edit pages please

Can please someone tell me what to do ??
