You are missing more, it appears an exception occurred somewhere in the database or os functions and the plugin stopped loading. I've done that loads in development. Maybe something was initializing and got an error - just a guess.
Here is an example using Windows commands but you will have to modify this for your screen. Also when the page loads, the captcha in this demo changes and you will have to manually line it up to see it working (or you can just see how it slides it but it may not solve it if its not lined up)
