I never said that it doesn't work don't understand me wrong, I had never errors like I read by a lot of people. Today I read that disable a plugin with a function is terrible. Well It was bothering me that I couldn't update a new update. So I give it a try again. Function deleted, update W3Total Cache and .. OMG it works. My Score on GTMetrix is just the same A 96 ... and Google speedpage is the same with the old version. And my website is loading fast, but a lot of options I don't understand like the cookie header somthing, so I leave all options just like the way it is.
Or there are ghosts on my server, or it was something else. For other people who have problems, old version or email Frederick. He is a good looking guy and very friendly to help.
