Doesnt cache & The pages do not match

So i just installed wp super cache and i have two issue.

1.The pages do not match! Timestamps differ or were not found!

I tried every solution i could find on google and to disable every plugin except this one.

2. In homepage source at the bottom

<!– Page not cached by WP Super Cache. No closing HTML tag. Check your theme. –>
