Delete Cache plugin "WP Super Cache" and I will install. Delete all folders in my FTP cache. Also delete the cache stored in cloudflare and still have the same problem.
After correcting all threats Wordfence seems to give me all right, but after a few hours back again the same. Wordpress update, if I update again gives me the same problems. For now I leave without threats Wordfence and asking me to update wordpress until you find the problem.
This is a picture asking me to update: https://lh4.googleusercontent.com/-dOlMf_eWT8I/UvoIZWSiOWI/AAAAAAAABdU/r-gC7SdN3co/w613-h117-no/Captura.JPG
