Early last week we upgraded my WordPress site to the latest version. Before there were no particular problems, but as soon as we upgraded, I began to receive about triple the amount of spam comments, and for the first time, I was receiving numerous pingbacks from other WordPress sites clearly set up by spammers.
Yesterday I logged in to my dashboard and went to delete the spam comments. As soon as I click an action (ie mark as spam), all the links on the whole WordPress dashboard turn green, and the action will not go through.
Furthermore when I try to post a blog, it will allow me to begin composing, but then if I try to Save Draft or after a certain period, it will take me to what looks like a PHP editing screen that is titled "Magic Include Shell 3.3.3". Also if I try to log out, it takes me to the same screen.
Per this thread...

...I downloaded brand new root files from WordPress, and replaced ALL of them in my root file except the wp-config file, meaning the whole wp-admin and wp-includes files, as well as all the other individual files in the root folder. It had no effect.
Help. Please.
