Missing Save Changes button again, and missing footer area

Even though I had deactivated the PHP Executable plugin earlier, it seems to be causing me trouble now anyway. The right sidebar widget admin area is missing its Save changes button, and on all my posts and pages, the very bottom is missing, where the copyright is. I've deactivated or deleted plugins that I thought might be causing this, but I'm stumped. Flynn, help? Could it be Any Code?
