Add a @ infront of wpdb->prepare !

to this:
I simply did this:
Either way, you would end up with one less "PHP Warning: Missing argument 2 for wpdb::prepare()" error message showing up, just work your way through the file that was mentioned in the error message, and you'll end up with everything being as before updating to WordPress 3.5
