Site showing strange text on top

Hi there
after installing WP Super cache i get strange text string like the following ones while the front-end is still viewable.
The administrative back end doesn’t work at all
It seems like some config file is not recognized.
My site is http://www.nonsolobellezza.it however i tried the plugin on my MAC (with MAMP). Also installed on live site and get the same mess.
Thank you for your help
