Just now, I had been in a horrible situation that I can see all my blog pages but when I go to http://worth2read.org/blog/wp-admin/ it appears as blank. That is I am completly locked out of the admin area.
I made a Google search for the solution and confused with lots of solutions that appeared.
However atlast I manged to get my admin page back, the solution that worked for me is as follows…
I checked the functions.php in my theme folder. There were some spaces at the top and bottom of the page. i deleted it.
I got my admin page back so that I can post this for you now.
I am posting it here thinking if anyone else came through such situation, it will be helpful for them.
