Fix WordPress Blank Screen [of DEATH!] After Upgrade

You have a site, a blog, a something. And you're using WordPress. Ok, that's cool. It's free and nifty, but you HAVE to keep it up-to-date. Nutty hackers and their b0ts are all over the net, HOPING people like YOU don't upgrade your site(s).

So after that warning, you want to upgrade to the latest version of WordPress. You upload your junk and go to your site and BOOM! Blank screen.

• Make sure your wp-config.php file has no white space(s) after the closing ?> mark.

Ok fixed that...

Next you try to login... and WHAMMMMMM! You're bounced back to the login screen. No errors, no messages in the UI... nuttin.

• Make sure that the wp-content/plugins folder has been renamed to something else, like wp-content/plugins_butt

Once you have logged in, rename that folder back to 'plugins' (you can also turn off the active plugins in the db, but it requires that you save its contents)

Those things helped me, I hope it helps you too!
