How to set Preload

Hello,

I use the free version of your plugin.

On the Settings tab I selected the following: Cache System, Preload, New Post, Update Post, Minify HTML, Minify Css, Combine Css, Combine Js, Gzip, Browser Caching and Disable Emojis.

In the right of Preload is an icon, a black circle like a gear instead of the blue circle with “i” in the middle. I would like to ask if Preload is correct set or not?

In Preload I have the following settings: Choose a Method – Default ( Contents from Newest to Oldest); Content Types –  I have checked Homepage Posts and Pages; Advanced Settings – I have checked Restart After Completed

On other sites I have the same settings but there not appear the “gear icon”. On other sites is selected also the New Post option.
