Many of the buttons in my wordpress dashboard/editing pages aren't working. For example, if I push "update" on a post, it doesn't do anything. Other buttons around the site aren't working either, such as buttons to delete plugins. I try clicking them but nothing happens. It all used to work but it doens't anymore. I tried clearing my cache, using a different browser, re-downloading the latest update, deleting plugins I'm not using, and rebooting my computer. Nothing's working. Any thoughts?
