It’s hard to tell which plugin you are using but it looks like some performance optimization plugin which is based on Google PageSpeed. Also this might be implemented by your hosting provider but I doubt that but theoretically it is possible.
Hi, where is the “Social Link” functions? I don’t find any on my menu section. There is only Pages, Post, Custom Link, Categories, and then as menu style the option “Social Menu” at the bottom.
I also tried the Jetpack social media icons, but nothing happens.
I am using some of the modified child themes that has some CSS code into it and plug in Movin made sometimes for some other function. Should I test with the Parent theme and/or copy something from the Parent theme to the child theme for the Social Link option to appear?
I think the custom CSS code added in the Customize mode had something to do with at least the Jetpack malfunction. Now when I erased the code(which intention was to make the text over the header/slider image to scale down, topic that was discussed here: https://colorlibsupport.com/t/scalingchange-size-of-the-slider-text-and-bars/) …it seem to allow the social sharing icons to posts. But still the sidebar icons are missing. Are they separate objects look for than Jetpack icons? And weird enough, the Custom mode “Social” has box to tick that makes them appear in the footer area that works. But not on the sidebar.
