Annie, I also occasionally experience problems when I click on Say Say Say at the top to return to the main page. It is a permanent glitch in the forum. I have begged the codemakers to fix it to no avail. When you get the "site not published" error message, just click on the back arrow (or alternately the forward arrow) and it should take you straight to the forum.
As for the problem with the blank pages, it could be it is loading at the bottom of the page instead of the top. Have you tried scrolling up? If that's not the issue, I'm not sure what's going on, but I will report it for you.
Thanks for your patience!
