Having Problem with Page analysis

After working on my wordpress website and creating my first sites I optimized one of my sites with the page analyses tool included in the editing functions of the site.
Two days later I just wanted to optimize the other sites I created but the page analysis isnt there anymore. It disappeared. I dont have a clue where it is.
I reinstalled the plugin but this action took no effect.
